Ground Based Remote Sensing of Aerosols Using AERONET in Indian Region

Abstract

Aerosols are defined as solid or liquid particles suspended in the atmosphere which directly affect the Earth's radiation budget, cloud properties, air quality, and human health. Aerosol Optical Depth/Aerosol Optical Thickness (AOD/AOT) is a measure of aerosol loading, integrated through the atmospheric column. In this paper, a comparison of AOD obtained from AErosol RObotic NETwork (AERONET) at Jaipur, Pune, Gandhi College, and Karunya University is made for the years 2017, 2018. Finally, the daily average AOD obtained for May 2018 over New Delhi IMD, Jaipur, Pune, Gandhi College, Karunya University is compared and results are discussed. The comparative study of the AOD trend over Karachi and Gandhi College during the period of September 2006 to August 2014 is also made.
