Study on the satellite and ground based aerosol measurements over Himalayan region

In this study, the evaluation of satellite retrievals with ground based aerosol measurements and a case study on hygroscopic aerosol transport is discussed. Latest aerosol product levels 1B and 2 (version 4.10) of Cloud-Aerosol LiDAR and Infrared Pathfinder Satellite Observations (CALIPSO) are evaluated with its earlier versions at a regional scale. A marked improvement is observed in the surface detection and tropospheric aerosol classification over the complex mountainous terrain in the latest version. A typical case on the measurements from ground-based sensors, in conjunction with CALIPSO, and reanalysis products is also discussed.
