Atmospheric aerosol and clouds play important role in weather and climate. A recent discovery of high altitude (~ 16km) Aerosol layer occurring during monsoon in the south Asian region using CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation) has started puzzling the atmospheric scientists. Very little is known on the composition and the formation mechanisms of this intense aerosol layer. This layer is of concern since it could play an important role on the climate and weather.
