Abstract

We present a systematic comparison of different analyses of satellite-retrieved extinction profile based on the satellite - measurements with those derived from ground based Lidar. Also compared is the Lidar-derived aerosol optical depth (AOD) with passive sensor derived from the Moderate Resolution Imaging Spectroradiometer (MODIS). The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) satellite data are used as these comparisons and that is a bit complex because spatial and temporal coincident data for clear sky conditions are needed for its comparisons to other Lidar data. Although limitation of the number of coincident dataset and expected errors are unknown, the satellite based aerosol extinction coefficients agree to those measured by ground-based Lidar within 0.02km-1. The two different satellite-derived AODs differ by 30% in comparison to the average of the coincident.
