This thesis focused on the retrievals of Land Surface Emissivity (LSE) from microwave data and thermal infrared data. (1) This thesis provides a method to retrieval LSE from the AMSR-E (Advanced Microwave Scanning Radiometer-Earth Observing System) and develops a Soil-Atmosphere Radiative Transfer Model (SARTM) to simulated brightness temperatures at satellite level. SARTM model is built from MonoRTM (MONOchromaticRadiative Transfer Model) and from AIEM (Advanced Integral Equation Model) models. In this study, the LSEs over whole China of year 2006 are estimated. (2) This thesis also presents an improved algorithm to retrieve LSE from SEVIRI (Spinning Enhanced Visible and Infrared Imager) data onboardthe MSG-2 satellite. Finally, this improved algorithm is applied to several MSG-2/SEVIRI datasets over a study area withinthe Iberian Peninsula region. It is demonstrated with some detailed cases that these improvements on the original LSE/land surface temperature (LST) retrieval methods are effective and reasonable

East Asia is the second largest source of mineral-type aerosols in the world after the Sahara. These can modify the Earth's radiative balance due to their properties of absorption and diffusion of atmospheric radiation. Therefore, precise information on the physico-chemical properties of desert dust is essential to understand and better quantify their impact on the atmosphere. In this context, this thesis aims to test the potential of a new methodological approach combining laboratory measurements and satellite remote sensing for better characterization of aerosols from desert and semi-arid surfaces. Its application concerns studying desert storm events in East Asia from the IASI space instrument.One of the major difficulties of this work comes from the fact that the mineral dust emitted in this region is emitted mainly above the continental surface and in the lower troposphere, which poses constraints linked, on the one hand, to a low sensitivity due to a lack of thermal contrast and on the other hand due to the great influence and variability of the Earth's surface emissivity (LSE). Thus, the first part of this work focused on improving the consideration of LSE by developing a new methodology from a set of average monthly emissivity data.Then, experimental extinction coefficients of pure minerals were linearly combined to reproduce a spectrum of Gobi dust, which made it possible to obtain the mineralogical mass fractions. In addition, from the IASI radiances, an optical thickness of Gobi dust was calculated, displaying characteristics identical to those measured in the laboratory. The linear combination of pure mineral spectra was then applied to IASI optical thickness, providing mineralogical mass fractions. Finally, the entire methodology was applied to two dust events during two different seasons and years: May 2017 and March 2021. The method made it possible to obtain the first spatial and temporal distributions of the chemical composition of desert aerosols. The average mass fractions obtained for particles from the Gobi Desert, Taklamakan Desert, and Horqin Sandy Land are close to mass fractions from the literature. In addition, these results on the chemical composition made it possible to link aerosols' spatial variability to dust emission sources, confirmed using a retro-trajectory model. In addition, comparing two IASI instruments on MetOp A and B showed good consistency, allowing us to consider the method's applicability to different MetOp platforms having the same instrument type. The results presented in this manuscript represent an important advance in improving the characterization of desert aerosols by space remote sensing, in particular concerning the analysis of the chemical composition

Sea surface infrared emissivity and reflectivity are important parameters in oceanic remote sensing, e. G. For deriving the sea surface temperature. They are both nearly constant for observation directions near zenith, but they vary largely for large grazing angles, because of the surface roughness. This thesis aims at calculating the sea surface infrared emissivity and reflectivity with accuracy. In addition, polarization is taken into account. Indeed, the phenomena of shadowing and multiple surface reflections are taken into account in the models through illumination functions without and with surface reflections. In order to validate developed models, a reference method, based on a Monte Carlo ray tracing algorithm, is used. Simulation results show very good agreements of the models with the ray tracing algorithm. Moreover, the agreement with emissivity measurements of the literature is improved if one surface reflection is considered. The criterion of energy conservation is better met by taking the sea surface reflections into account in the model. Thus, these results clearly show the usefulness of considering shadowing and surface reflections in the modeling

In order to study the dynamics of the Earth's outer core, we compute core surface flows from observations of the main magnetic field. The relevance of these computations is confirmed by the similarities of the flows obtained with two independent methods and the results of different synthetic tests. Two different kind of observations are used : ground-based observations for the time period 1590-1990 and recent high-resolution satellite observations. We thus obtain a time series of the historical flows as well as a detailed model of the present flow. The evaluation of errors associated to these flows enable us to identify their reliable features. The velocity fields we obtain are in good agreement with different phenomena appearing in 3D-simulations of core dynamics. We also show that geomagnetic jerks have an explicit signature in core surface dynamics. In the last chapter, a variational data assimilation method for the study of the Earth's core is introduced

The aim of this study is to build a 3-D attenuation model of Earth's upper-mantle using a unique datasetbuilt by Debayle & Ricard (2012). This dataset is among the largest in the world: more than 375,000seismograms were analyzed to extract Rayleigh-wave attenuation and velocity measurements for thefondamental mode and the five first harmonics between 40 and 240 s periods.First, attenuation measurements are processed to extract the effects of geometrical attenuation and offocusing and defocusing, in order to minimize the influence of errors on the seismic source, to avoidpotentially incorrect data, and to cluster redondant measurements. Then, measurements are regionalizedto obtain Rayleigh-wave maps for each mode and each period. The last step is the inversion of thesemaps to obtain the depth dependent attenuation. Eventually, we obtain QsADR17, a 3-D model of Swaveattenuation in the upper mantle.QsADR17 is correlated with surface tectonics down to 200 km depth, with low attenuation under thecontinents and high attenuation under the oceans. High-attenuation anomalies are found under oceanicridges down to 150~km depth, and under most of the hotspots at larger depth down to the transitionzone. A large high-attenuation anomaly at 150~km depth under the Pacific ocean suggest that thermalplumes pound into the asthenosphere. We also detect compositional heterogeneities at the base of thecratons and in active areas

Emissivity is an optical property of materials, related to their ability to emit electromagnetic radiation. This PhD is devoted to retrieving emissivities of outdoor surfaces from high spectral resolution (4cm-1) spectroradiometric measurements at ground level, in the 750 cm-1 to 3500 cm-1 (3-13µm) spectral range. The main objective of this work, which combines theoretical and experimental approaches, is to define and assess a methodology. Two emissivity-temperature separation techniques are addressed, the Spectral Smoothness Method (SpSm) and the Multi-Temperatures Method (MTM), with particular attention paid to extending their usual domain of application on the short wavelength side beyond 1250cm-1. Sources of errors are identified and an experimental approach to mitigate errors on the determination of the irradiance of the surface is proposed. A new method, named Smoothness and Continuity (SmaC), is introduced, which takes into account the directional behaviour of the observed surface, to improve emissivity retrieval in the mid-infrared band (MWIR from 2000 to 3000 cm-1)To quantitatively assess the retrieval methods and validate the measurement protocol, a field campaign, that took place in June 2004, aimed at providing an error budget of the methods by measuring emissivities of several samples at different times of day. SpSm, applied to the campaign measurements, provides very good results in the LWIR band (from 750 to 1300 cm-1). In the MWIR band, systematic spectral discontinuities and deviations to laboratory measurements are observed in the retrieved spectra. This is interpreted as a manifestation of angular dependence of emissivity: the new SmaC method, through the introduction of a surface form factor, leads to significantly improved results. The standard deviation of the retrieved emissivity spectra over all measurements and samples is less than 0. 01 in LWIR and less than 0. 03 in MWIR. MTM results are less satisfactory than SpSm ones, due to ill-conditioned system of equations. Finally, a numerical analysis is carried out to confirm and validate SmaC hypothesis and findings
