Full textThe surface solar irradiance (SSI) is seldom measured and several methods have been developed for its assessment from images taken by geostationary or polar-orbiting satellites. In current methods, so-called inverse, the signal received by the satellite is inverted to derive the radiation on the ground. It is felt that as a whole, limits of such methods are presently reached in terms of accuracy. Consequently, a new paradigm is studied based on a direct modeling of propagation of solar radiation through the atmosphere. In this thesis, we design a new method -called Heliosat-4- based on the radiative transfer model libRadtran; it benefits from advanced products derived from recent earth observation missions. For this purpose, we • establish by the means of a sensivity analysis, the necessary inputs of any method based on radiative transfer model, • establish that SSI for a cloudy atmosphere can be considered as equal to the product of the SSI obtained under clear-sky and a function of the cloud extinction and ground albedo contribution, • implement approximations of radiative transfer equation, for clear and cloudy atmosphere, allowing rapid calculations. Heliosat-4 is free from empirical parameters, easy to implement and deliver simultaneously direct, diffuse components and spectral distribution of irradiance. These characteristics, while necessary for various applications, are rarely provided. The first results of the validation of the new method with ground measurements are encouraging: observed performances are similar to those of current methods.

Full textWestern Central Africa, home to the densest forests of the Congo Basin - the second largest tropical forest massif after Amazonia - is characterized by an equatorial climate with high temperatures, a bimodal rainfall pattern and, a long and cloudy dry season from June to September. Despite its ecological importance, the climate variability of this region has been less studied compared with other parts of the African continent, mainly because of the scarcity of in-situ observations.Recognizing these challenges posed by the lack of in-situ data, this study explores the climate variability in Western Central Africa through the lens of surface solar radiation, a key parameter for the functioning of tropical forests. In this context, this thesis aims to establish an initial climatology of surface solar radiation for the region, to document its variability, particularly during the cloudy dry season from June to September, and to assess the performance of satellite products, reanalyses and CMIP6 climate model simulations.In the first part, an evaluation of eight satellite products for estimating solar radiation (CERES-EBAF, CERES-SYN1deg, TPDC, CMSAF SARAH-2, CMSAF CLARA-A2, CAMS-JADE, WorldClim 2 and ERA5 reanalysis) reveals differences in the spatiotemporal fields. While successfully capturing mean annual solar radiation cycles, the products show regional variations, highlighting the impact of atmospheric parameters on the accurate estimation of solar radiation. In addition, all the products except WorldClim 2 agree that the Atlantic coast receives less solar radiation than the other regions of Central Africa. The performance of these products is also assessed against in-situ measurements based on four types of solar radiation diurnal cycle - Obscure, Obscure AM (morning), Obscure PM (afternoon) and Bright days. The products correctly represent the shape of these four types, but with a larger amplitude.The second part focuses on studying the interannual variability and trends in solar radiation during the June-September cloudy dry season, highlighting notable differences between CMSAF SARAH-2 satellite product and ERA5 reanalysis. The study also made it possible to identify the onset and cessation dates of the dry season based on solar radiation, and establishing a significant relationship between surface temperatures of the equatorial Atlantic ocean and the onset of the dry season.In the final part, the capacity of CMIP6 global climate models to reproduce average levels of solar radiation in the region was assessed. The results highlight sub-regional disparities in model performance. The models used in this study underestimate solar radiation in the south-west of Gabon-Congo, while they overestimate it in the north-east, mainly from april to december. The largest differences were observed during the october-november rainy season. These disparities seem to be caused by cloud cover, in particular low- and medium-level clouds, which have a significant influence on solar radiation, although the relationship varies according to the models. This section also highlights the teleconnection between the surface temperature of the equatorial Atlantic ocean and solar radiation in the models, which varies between the coastal and inland areas of Gabon, underlining the need to use regional climate models
