Different strategies to retrieve aerosol properties at night-time with the GRASP algorithm
International audience This study evaluates the potential of the GRASP algorithm (Generalized Retrieval of Aerosol and Surface Properties) to retrieve continuous day-tonight aerosol properties , both column-integrated and vertically resolved. The study is focused on the evaluation of GRASP retrieval...

International audience This study evaluates the potential of the GRASP algorithm (Generalized Retrieval of Aerosol and Surface Properties) to retrieve continuous day-tonight aerosol properties , both column-integrated and vertically resolved. The study is focused on the evaluation of GRASP retrievals during an intense Saharan dust event that occurred during the Sierra Nevada Lidar aerOsol Profiling Experiment I (SLOPE I) field campaign. For daytime aerosol retrievals, we combined the measurements of the ground-based li-dar from EARLINET (European Aerosol Research Lidar Network) station and sun-sky photometer from AERONET (Aerosol Robotic Network), both instruments co-located in Granada (Spain).
