Environmental context Atmospheric chlorine radicals can affect the chemical composition of the atmosphere through numerous reactions with trace species. In urban atmospheres, the reactions of chlorine radicals can lead to effects such as increases in ozone production, thus degrading local and regional air quality. This review summarises the current understanding of atmospheric chlorine chemistry in urban environments and identifies key unresolved issues. Abstract Gas phase chlorine radicals (Cl•), when present in the atmosphere, react by mechanisms analogous to those of the hydroxyl radical (OH•). However, the rates of the Cl•-initiated reactions are often much faster than the corresponding OH• reactions. The effects of the atmospheric reactions of Cl• within urban environments include the oxidation of volatile organic compounds and increases in ozone production rates. Although concentrations of chlorine radicals are typically low compared to other atmospheric radicals, the relatively rapid rates of the reactions associated with this species lead to observable changes in air quality. This is particularly evident in the case of chlorine radical-induced localised increases in ozone concentrations. This review covers five aspects of atmospheric chlorine chemistry: (1) gas phase reactions; (2) heterogeneous and multi-phase reactions; (3) observational evidence of chlorine species in urban atmospheres; (4) regional modelling studies and (5) areas of uncertainty in the current state of knowledge.

Abstract This essay examines urban atmospheres and emotions in the 1898 essay collection London Impressions by British writer, poet and suffragist Alice Meynell. I argue atmospheres are spatialised emotions and investigate the atmospheric dimension of Meynell’s text and her impressions, through a vocabulary of immersion and movement. Within her own manipulation of a ‘visual’ vocabulary, Meynell transforms impressions into atmospheres, the visual into sensorial, moving from the painterly to atmospheric experience, notably through the medium of fog and smoke and other climate indicators. I argue urban atmospheres are the main feature the text brings forth (even through – and perhaps especially because of – the filter of the written word). By probing the application of the history of emotions’ methodologies within architectural and urban history, I argue the concept of ‘atmosphere’ is a productive analytical category to examine visual and textual sources.

In this paper I seek to initiate a research agenda on mega-urban airs that comprehends their atmospheres as simultaneously meteorological and affective ( McCormack, 2008 ), an agenda which seeks to apprehend megacity air/atmospheres in their vitality, corporeality and expressiveness. This paper attunes to the close and expressive substances that make up immersion in a material-affective ecology of a place, the qualities of the city that seep and imbue its material and biological fabric with affect. There is a growing body of work and literature to aid us from traditions in continental aesthetic theory, French urban sociology and architecture, and an emergent cultural geographic field of atmospheric enquiry. The paper develops such an approach to megacity air in three main ways. First, air tells us about difference. In the testimony of pollutants and choking effluvium, an analysis of air reveals who belongs and who does not, who is deserving and who is not in a constellation of megacity inequality. The atmosphere puts the megacity apart from other urban and political forms. Second, closely related to the issues that circulate around a geopolitics of verticality and the technocratic security concerns of volumetric conceptions of territory, air/atmospheres constitute an environmental ecology of security threats and crisis that thwart megacity life and justify environmental policies as ‘security’ (see Zeiderman, 2013). Third, the paper argues how megacities are increasingly productive of secessionary atmospheres, often by removal and exclusion, which are not entirely separate from other atmospheric security concerns.

Within the context of recent debates around urban atmospheres, this article examines the situatedness and partiality of urban experiences. Drawing on an ethnographic study of the Smithfield Market area, a neighbourhood undergoing a period of rapid urban regeneration as part of the ‘Culture Mile’ in the City of London, we explore how different individuals experience the changing feel of place. By focusing on the felt body, the article analyses the ways in which individuals with different attachments to the neighbourhood respond to the impending urban change and draw on selective temporal modalities of atmospheres in order to make specific claims to place. In particular, we identify three temporal modalities of atmospheres: the selective feel of the past, the contentious present feel and the ambivalent future feel. The article thus argues that studies of urban atmospheres need to pay more attention to the manifold bodily capacities, personal and social histories which mediate and position in diverse ways how places are experienced. More generally, this article makes an intervention into debates on urban atmospheres by analysing empirically how the variable interactions between sensory and temporal qualities produce diverse atmospheric constellations for different individuals.

In this debate, we claim that few Egyptian scholars are considering issues of phenomenological critiques addressing adequately the atmosphere of cities and places, and that Egyptian urban design education does not address the possibility of teaching through commentary of this kind. This article examines the dilemma of using the term “atmospheres” in urban design education. It theorises the nature of this relationship, developing an analytical framework creating the architecture of the city as similar as the artworks through which to investigate them related through their aspects—ideas, themes, and dramatic text—and those overarching effects of the technical elements. The question is: how can one use the artworks in urban design teaching? This article discusses the atmospheres in many artworks of Western and Egyptian thought to explore the effect of the architecture of cities in creating the atmospheres of the cities. The conclusion aims to reach some of the lessons learned by analysing artworks that have achieved a different atmosphere in specific places.

This paper examines how the combined prism of contemporary art and the notion of atmosphere may offer alternative perspectives on our encounters with places and practices of surveillance. Specifically, this article investigates the atmospheres of surveillance surfacing in the video installation Safe Conduct (2016a) by British contemporary artist Ed Atkins. The artwork recreates the well-known situation of going through an airport security check. Through a combination of visual narrative and a soundscape blending the sounds of the conveyor belt and X-ray machines with heavy breathing and Ravel’s Boléro, the work builds up an uncanny anticipation of something awful. Death and violence linger at its edges, and a disquieting atmosphere fills the exhibition space. The objective of the article is twofold: First, it explores the shifting and ambiguous atmospheres produced by contemporary surveillance practices through an immersive reading of the artwork Safe Conduct. Second, and connected to the first, it offers an experimental methodology of written vignettes responding to the embodied, aesthetic experience of atmospheres of surveillance. The article concludes that being more sensitive to the atmospheres of surveillance in our environment can give us a space to think critically about how these atmospheres affect us, how they are absorbed bodily, and how they attune our being: how surveillance is “in the air.”

This article argues that the notion of affective atmosphere provides a privileged access to the study of organizational affect as it relates to a spatial ontology of ‘being-together-in-a-sphere’. Drawing on the study of affective atmospheres in philosophy and cultural geography, we develop a conceptual positioning from which to analyze a musical intervention in the streets and squares of Berlin. The study traces the preparation and enactment of a 2-day music event that breaks with the emotional experience of a ‘mainstream’ classical concert, and instead intervenes in urban atmospheres by mingling music performances with everyday urban life in an attempt to affect chance spectators. Tracing how the concert’s atmospheres emerged through a series of encounters between various bodies and their specific affective capacities, the analysis emphasizes the tension between the possibility of designing and crafting atmospheres and its emergence in erratic, ephemeral, and excessive ways. Therefore, we propose that affective atmospheres make perceptible the potentialities of organizational space and give scope to our feelings as we experience their spatial recomposition. In the conclusion, we emphasize affective atmospheres as a key concept for the critical study of affect, as it advances a politics that attends to new possibilities of feeling and acting collectively in spaces of organizing.

The principles of linear perspective geometry were applied to both the representation and the form of the Renaissance city to reflect the collective proprietorial ambitions of church and state. Anamorphosis was developed by intellectual dissidents as a drawing mechanism and as a counter to the previous representational constraints imposed by linear perspective. The contemporary city image relies upon on an array of pixels mediated by technology to foster existing relationships between power and place. The paper argues that digital technologies initiate anamorphic viewing conditions that correspond to previous attempts to destabilise the covert ambitions of linear perspective. By presenting digital anamorphic representations of contemporary urban space, it shows how the temporal nature of the image and the pixel-based geometry of the digital array not only contest the promotional city view but multiply the opportunity to understand previously unexplored qualitative, atmospheric properties of urban space.

This article is devoted to a relatively new aesthetic concept, the concept of atmosphere. In the second half of the 20th century, due to the overcoming of the understanding of the aesthetic as a field of art and the emergence of the tendency to appeal to sensual experience, the idea that aesthetic perception and aesthetic experience are possible not only in the context of art events, but also in the space of everyday life is becoming increasingly relevant. The aesthetics of atmosphere arises from the aesthetics of everyday life. The first to declare the concept of atmosphere as a separate aesthetic theory was H. Böhme (1937–2022). The immediate predecessors of the concept of atmospheres are the theoretical positions of G. Schmitz and W. Benjamin. The aesthetics of atmospheres explores the states that arise in the process of the relationship between the subjective and the objective factors and in their material, emotional interaction. This article analyzes H. Beme’s concept of atmosphere, as presented by him in his works: “‘Atmosphere’ as a fundamental concept of the new aesthetics”, “Atmospheric Architectures: The Aesthetics of Felt Spaces”, “Architektur und Atmosphäre”. A special place in H. Beme’s aesthetic theory of atmospheres is occupied, first, by the concept of “ecstasy of things” introduced by him, which allows us to speak of the relatively objective nature of atmospheres, and, second, by the problem of the production of artificial atmospheres. Most studies of atmosphere as an aesthetic category consider atmosphere in the context of architecture, urban environment, design, etc. This article attempts to explore the atmosphere in digital space. At present, digital space has already lost its representational and in principle auxiliary position in relation to the human being, and has become a space for the realization of possibilities, the functioning of which was not represented in the human being’s being. The specific possibilities of the digital require a special analysis of the aesthetic, capable of exploring the digital space in its entirety. The article suggests that the concept of atmospheres is a productive way to work with digital space, which is shown on the example of such digital space phenomena as metavelves and ASMR-video. The study showed that the concept of atmospheres is convenient for working with digital space, especially due to the fact that with its help it is possible to carry out successful analysis not only of visual and auditory components (characteristic for classical aesthetics), but also of other ways of aesthetic perception.

This paper studies atmospheres of stillness in a contested urban public space known as the ‘Bearpit’. The purpose is to provide a nuanced account of stillness and its relationship to atmosphere. Drawing on an ethnographic examination of the Bearpit, the paper finds that the positive and beneficial aspects of stillness can be found in unexpected and unconventional places. However, there is no single, unifying experience of stillness, but rather a plurality of ‘stillings’. The paper highlights three forms of stillness distilled from study of the site – calmness, control and withdrawnness – and demonstrates how these modalities emerge from and contribute to the construction of atmospheres in the Bearpit. Moreover, these atmospheres have direct political consequences for those who take part in city life. The paper’s contribution is found in the advancement of non-anthropocentric understandings of atmosphere and the development of stillness as a way of understanding city life.

An architectural filter is a porous material construction that regulates transverse visual relationships, and establishes degrees of connection through the intervention of light and gaze. Filtering boundaries display variable proportions of mass and air, which are instrumental to the production of the spatial experience behind the mediation of matter and geometry. A filter's structural system synthesizes geometric relations with the capacity to cause architectural atmospheres, as a result of the active border that is technically precise and sensorially ambiguous at the same time. The text sustains that the emerging atmospheres behind the filter cannot take place without a previous, precise geometric production; the poetic dimension of filtering strategies originates from its capacity to transform the concrete geometry of its contour conditions and controlled material execution into an unexpected atmosphere of emotional and incommensurable qualities.

The aim of this work was to compare the corrosion products formed on carbon steel plates submitted to atmospheric corrosion in urban and industrial atmospheres with those formed after accelerated corrosion tests. The corrosion products were characterized by X-ray diffraction, Mössbauer spectroscopy, and Raman spectroscopy. The specimens were exposed to natural weathering in both atmospheres for nine months. The morphologies of the corrosion products were evaluated using scanning electron microscopy. The main product found was lepidocrocite. Goethite and magnetite were also found on the corroded specimens but in lower concentrations. The results showed that the accelerated test based on the ASTM B117 procedure presented poor correlation with the atmospheric corrosion tests whereas an alternated fog/dry cycle combined with UV radiation exposure provided better correlation.

This paper describes the ability of artificial neural network (ANN) models to simulate the pollutant dispersion characteristics in varying urban atmospheres at different regions. ANN models are developed based on twelve meteorological (including rainfall/precipitation) and six traffic parameters/variables that have significant influence on emission/pollutant dispersion. The models are trained to predict concentration of carbon monoxide and particulate matters in urban atmospheres using field meteorological and traffic data. Training, validation, and testing of ANN models are conducted using data from the Dhaka city of Bangladesh. The models are used to simulate concentration of pollutants as well as the effect of rainfall on emission dispersion throughout the year and inversion condition during the night. The predicting ability and robustness of the models are then determined by using data of the coastal cities of Chittagong and Dhaka. ANN models based on both meteorological and traffic variables exhibit the best performance and are capable of resolving patterns of pollutant dispersion to the atmosphere for different cities.

Walkability is becoming one of the central themes in urban research. It is among concerns of city’s designers. Several studies have shown that walking in the city preserves the environment and people’s health. Walkers merge into the city in a total, i.e., effective, sensory, cultural, etc. They perceive the city with their senses. So then, the urban morphology of the street as well as the architecture of the buildings that delimit them influence the sensory perception of the pedestrian. On the other hand, another notion having a considerable development in the last decades is the urban atmosphere. It highlights the other sensory dimensions (thermal, sound, olfactory, tactile, etc.) of the urban space and goes beyond its visual aspect. This research aims to study the walkability in one of the most frequented streets by pedestrians in Bechar city (south of Algeria). Its main objectiveis to know how walkers perceive the urban environment of the street by focusing on their sensory experience. It combines two notions: walkability and atmospheres in the urban space. We used several research techniques: morphological and sensory analysis of the street, participant observation, photo-elicitation interview and survey. The research results attest that there is a strong relationship between the urban environment of the city and walkability. The components of the street such as dimensions, architecture of the buildings that limit it and the prevailing atmospheres have a direct impact on walking in the city and sensory perception of pedestrians. Then, this research is not limited to the visual aspect of urban environment of the street but it emphasizes other sensory dimensions which are often neglected by architects and urban designers of Bechar city.

This article is drawn for my experience busking at Nørreport Station, a busy transit hub in the centre of Copenhagen, for one afternoon in the spring of 2016. I use narrative and descriptive writing to express the relationship between myself and the environment as a performative milieu. The article looks at theories of affect, atmospheres, and the influence of sound in the busking pitch. It considers the discourse surrounding busking and how my performance experience contributed to appreciations of its meanings. It has been said that street music performance can create emotions, atmospheres and encounters in unlikely and forbidding urban settings. My experience at Nørreport Station challenged these notions. This article avers that new ways of assessing the success of musical interventions in the city should be considered alongside with appreciating how music can be a subtle and meaningful atmospheric and affective influence on urban space.

Abstract With toxic air emerging as one of the biggest risks facing urban residents globally, alongside the possibilities of designing “domes” of purified atmospheres, air has lately emerged as a productive object of critical urban inquiry. This essay delves into the manner in which air is being thought and written about, the various attempts to govern it, the production of identities and solidarities around it, and what it means to live with toxic air across urban regions. It argues that the debate on urban air contributes strongly to current thinking around questions of citizenship, science, and justice.

This article uses atmosphere theory to describe the revolutionary events on Ukraine’s Maidan Nezalezhnosti as they unfolded from November 2013 to February 2014. Like other recent occupation movements (Tahrir Square, Gezi Park, Zuccotti Park), the Maidan protestors created a vast infrastructure that supported large-scale protest and daily life on the square. I argue that atmosphere, or the feeling of place, was important to the makeup of Maidan. Like other occupation movements, Maidan became a “world” unto itself because it generated unique feelings that held the place together. Drawing on atmosphere theorists Peter Sloterdijk and Gernot Böhme, I describe the atmospheres of Maidan, show how these atmospheres were generated, and then describe how these atmospheres influenced the course of the revolution.

As an artist and junior researcher for the project “Public Transport as Public Space,” my aim is to understand atmospheres on urban public transport and the ways in which they can be changed through performative public art practice. Indefinite yet powerful, atmospheres, which emerge in the relation between a perceived environment and perceiving bodies (Böhme 2017), can be created deliberately through aesthetic work and used as a tool for shaping certain experiences and behaviors in public space (Allen 2006). For instance, visually attractive public artworks permanently integrated into the public transport environment may create atmospheres of safety and comfort, navigating passengers through this regulated public space. On the other hand, on public transport, where unacquainted people must travel shoulder to shoulder, different atmospheres emerge not only through material modifications but also through unexpected encounters and events (Bissell 2010). In this sense, performative public art interventions can intentionally “drum up the ambience” (Thibaud 2015) and imbue the atmosphere of commutes with elements that are surprising and out of the ordinary. This paper outlines some of my art projects, which aim to carefully disrupt casual rides on public transport by creating moments of strangeness and humor.

This article calls for a consideration of the reuse aesthetics of urban ruins in terms of cultural valuations related to the political status of social practices. In the context of debates on ruins in the field of memory studies and along the division between politics and the political, I argue for the recognition of affective atmospheric practices based upon performative knowledge-making and reenactments of atmospheres from the past. As demonstrated by an example of reuse in Berlin in the 2000s, these practices recall rituals and routines from the pasts of ruins by performatively exploring their futures. This position will be critically situated within the debate about “socially engaged arts” and the neoliberal “creative city” policies in the city of Berlin. It will also be presented as a cultural value-making in conflict with the paradigm of historical reconstruction in architecture and planning aimed at creating architectural replications from the archive. The article concludes with a reflection on reenactments as cultural value-making, a perspective that may have an effect on heritage policies.

Abstract. Sulfuric acid (SA) is a governing gaseous precursor for atmospheric new particle formation (NPF), a major source of global ultrafine particles, in environments studied around the world. In polluted urban atmospheres with high condensation sinks (CSs), the formation of stable SA–amine clusters, such as SA–dimethylamine (DMA) clusters, usually initializes intense NPF events. Coagulation scavenging and cluster evaporation are dominant sink processes of SA–amine clusters in urban atmospheres, yet these loss processes are not quantitatively included in the present parameterizations of SA–amine nucleation. We herein report a parameterization of SA–DMA nucleation, based on cluster dynamic simulations and quantum chemistry calculations, with certain simplifications to greatly reduce the computational costs. Compared with previous SA–DMA nucleation parameterizations, this new parameterization was able to reproduce the dependences of particle formation rates on temperature and CSs. We then incorporated it in a three-dimensional (3-D) chemical transport model to simulate the evolution of the particle number size distributions. Simulation results showed good consistency with the observations in the occurrence of NPF events and particle number size distributions in wintertime Beijing and represented a significant improvement compared to that using a parameterization without coagulation scavenging. Quantitative analysis shows that SA–DMA nucleation contributes significantly to nucleation rates and aerosol population during the 3-D simulations in Beijing (>99 % and >60 %, respectively). These results broaden the understanding of NPF in urban atmospheres and stress the necessity of including the effects of coagulation scavenging and cluster stability in simulating SA–DMA nucleation in 3-D simulations. Representing these processes is thus likely to improve model performance in particle source apportionment and quantification of aerosol effects on air quality, human health, and climate.

NASA’s Gateway to Astronaut Photography of Earth contains over 30,000 photos of ~2500 cataloged urban lightscapes (anthropogenic night light) taken from the International Space Station. A subset of over 100 of these multispectral DSLR photos are of sufficient spatial resolution, sharpness and exposure to be potentially useful for broadband spectral characterization of urban lightscapes. Spectral characterization of multiple urban lightscapes can provide a basis for quantifying intra and interurban variability in night light brightness, color and extent, as well as the potential for change analyses. A comparative analysis of simulated atmospheric transmissivity from the MODTRAN radiative transfer model indicates that the spectral slopes of transmissivity spectra are relatively insensitive model atmospheres, with variations in atmospheric path length and aerosol optical depth primarily affecting the bias of the spectrum rather than the slope. A mosaic of 18 intercalibrated, transmissivity-compensated RGB photos renders a spectral feature space bounded by four clearly defined spectral endmembers corresponding to white, yellow and red light sources, with brightness modulated by a dark background endmember. These four spectral endmembers form the basis of a linear spectral mixture model which can be inverted to provide estimates of the areal fraction of each endmember present within every pixel field of view. The resulting spectral feature spaces consistently show two distinct mixing trends extending from the dark endmember to flat spectrum (white–yellow) and warm spectrum (orange) sources. The distribution of illuminated pixels is strongly skewed toward a lower luminance background of warm spectrum street lighting with brighter lights, generally corresponding to point sources and major thoroughfares.

First introduced by Martin Heidegger in his later philosophical work, over the decades the concept of dwelling has acquired a fundamental importance in architectural theory. Its “classic” status, however, along with its centrality in post-modern architecture, has largely prevented the unfolding of an open discussion on the present-day validity of this notion. Similarly, the work of another cult author such as Gaston Bachelard, whose book The Poetics of Space is equally revered as a classic, appears to be uncritically espoused outside of a proper contextualization. While dwelling does represent a fundamental driver of human presence in the world, these two primary accounts and their implications in design should be discussed against other complementary or antagonistic models, such as those proposed by Deleuze and Guattari, Sloterdijk and Schmitz. Each of these authors defines his position vis-à-vis Heidegger’s original proposal, while opening to different repercussions on the practices of design.
