CALIPSO Land Surface Mapping Principle and First Results
Résumé
The quantification of aerosol radiative properties, especially aerosol optical depth (AOD) is of high importance for climate change analysis. Several approaches are now possible, using active (lidar) and passive (spectro-radiometers) sensors. The objective of this study is to analyze the potential of using the CALIPSO lidar land surface return signal to improve the AOD retrieval. First, an analysis of land surface properties is explored and then an application to AOD retrieval is presented.
