Bayer, Andreas Paul Adolf. « Biomass forest modelling using UAV LiDAR data under fire effect ». Master's thesis, ISA, 2019. http://hdl.handle.net/10400.5/21269.
Texte intégralThe main goal of the study is to analyse the possibility of quantifying the loss of biomass in burned forest stands using Light Detection and Ranging (LiDAR) data. Since wildfires are not uncommon in Mediterranean areas, it is useful to quantify the magnitude of fire damage in forests. With the use of remote sensing, it is possible to plan post-fire recovery management and to quantify the losses of biomass and carbon stock. Mata Nacional de Leiria (MNL) was chosen, because, after the fire in October 2017, it showed areas with low and medium-high fire severity. MNL is divided in several rectangular management units (MU). To achieve our objective, it was necessary to find a MU with burned and unburned areas. In this selection process, we used Sentinel-2 images. The fire severity was estimated by deriving a spectral index related with the effects of fire and to compute the temporal difference (pre- minus post-fire) of this index, the delta normalized burn ratio (DNBR). Forest inventory was carried out in four plots installed in the selected MU. Allometric equations were used to estimate values of stand aboveground biomass. These values were used to fit a relationship with data extracted from LiDAR cloud metrics. The LiDAR data were acquired with a VLP-16 Velodyne LiDAR PUCK™ mounted on an Unmanned Aerial Vehicles (UAV) at an altitude of 60 m above the ground. The point clouds were then processed with the FUSION software until a cloud metrics was generated and then regression models were used to fit equations related to LiDAR-derived parameters. Two biomass equations were fit, one with the whole tree metrics having a R² = 0,95 and a second one only considering the tree crown metrics presenting a R² = 0,93. The state of the forest (unburned/burned) was significant on the final equation

Texte intégralAs the understanding of the interactions between stratospheric ozone chemistry and climate change progresses, the consequences of both temperature change and perturbations in stratospheric aerosol loading are becoming a topic of major scientific interest.It is well established that volcanism is the main source of stratospheric aerosols and that major volcanic episodes are associated with negative ozone anomalies. However, the high latitude effect of an overload of sulphate aerosols, precursors of polar stratospheric clouds (PSC), remains poorly understood.In addition, stratospheric injections of carbonaceous aerosols have been observed during major fires in recent years. In Canada in 2017 and Australia in 2020, aerosol masses comparable to those emitted by moderate volcanism were reported. This is of great scientific interest, as carbon does not naturally occur in the stratosphere and the effects of its significant intake are yet to be studied. Also, climate change is expected to favour the occurrence of major fires, adding the question of long-term trends in aerosol loading to the need to finely characterise the effect of such a disturbance.PSCs, formed on aerosols, are the precursors of seasonal ozone destruction and are at the heart of these issues. Lidar is a suitable instrument for studying these condensed phases. Using the lidar at the French Antarctic station Dumont d'Urville (DDU) and relevant space instruments, this thesis investigates trends and processes related to PSCs and stratospheric aerosol perturbations.Measurements acquired at DDU use different classifications of PSCs to illustrate fine processes that are only accessible through the geometry of a ground-based instrument. The parameterisation of the PSCs is based on a concise and representative classification, and the coastal location of the station is an advantage due to the high variability of the particle observations it allows. A trend in the number of PSC days per year at DDU from 2007 to 2020 is established by combining lidar and temperature measurements. This trend, of -4.4 PSC days per year per decade, reflects an opposite trend in stratospheric temperatures over this period. The latter, recently confirmed by other studies, raises questions about long-term trends in the context of climate change.The Australian fires in 2020 injected an unprecedented mass of aerosols into the stratosphere, some of which was transported to the high southern latitudes. The DDU lidar was able to probe these aerosols from January to October 2020. This allowed a rich characterisation of the plumes over time. Their presence within the vortex was confirmed and raises the delicate question of the interactions between carbonaceous aerosols and PSC. The high ozone depletion reported at DDU in October 2020 can only be compared to the year 2015, marked by an aerosol overload due to the Calbuco eruption. We also highlight the technological challenge around aerosol speciation on fine signatures.In order to adapt to recent scientific questions, a field campaign allowed the evolution of the lidar installed at DDU towards a multispectral infrared / visible / ultraviolet laser source. This configuration offers new possibilities, including access to granulometry that can directly resolve aerosol and cloud speciation. The historical eruption in Tonga in January 2022 injected a large amount of aerosols, partly detected at DDU from February to September 2022. This thesis therefore includes work on this event using field instrumentation as a technical and especially scientific perspective for the study of aerosols and clouds at high latitudes

Texte intégralEm Portugal continental, os incêndios florestais são considerados a maior e mais grave causa de deterioramento da floresta e por isso a introdução de mecanismos de gestão florestal e monitorização da biomassa são imperativos para um futuro melhor. No entanto, realizar estudos de campo em grande escala é uma tarefa muito dispendiosa e demorosa. Em alternativa, através da deteção remota por vias de um LiDAR torna-se possível mapear, com elevado rigor, parâmetros florestais como altura das arvores, diâmetro do tronco ou comprimento da copa da arvore de modo a proceder a outras relevantes estimações como a biomassa. Neste sentido, esta dissertação teve como objetivo o desenvolvimento de um sistema capaz de, através de algoritmos e filtros de processamento de nuvens de pontos, como remoção de outliers estatístico, filtros morfologicos progressivos e segmentação por crescimento de regiões anexas , extrair com detalhe, um modelo digital do terreno e detetar corretamente o número de arvores numa determinada área, procedendo à medição de algumas variáveis interessantes do ponto de vista do inventário florestal. Assim, testando dados de diferentes características, o nosso método de deteção obteve resultados positivos, com todas as taxas deteção média superiores a 80 %.
