Abstract

The present study aims to explore the aerosol optical depth- an index of air quality, using the satellite observations over Tibetan Plateau (TP). The study is significant as the plateau exerts strong thermal forcing over Asian monsoon region. The atmospheric and hydrological cycle of the plateau has been changed over the years due to climate change effect. As the aerosols are one of the major component of climate change of any region the present study explores the variation of aerosol optical depth over the TP. Long term (2003-2019) Aqua and Terra MODIS Collection 6.1 Combined Deep Blue (DB) and Dark Target (DT) AOD observations are analyzed to study the seasonal variation of AOD over Tibetan Plateau. The AOD values are found the highest in pre-monsoon season over TP.
