Dr. Abhijit Chatterjee is currently working as an Associate Professor in Environmental Sciences Section with the expertise in Atmospheric Chemistry, Air Pollutants and Air Quality, Bio-geo-chemistry of the environment and especially focusing on the high altitude sub-tropical Himalayan ecosystem and tropical urban/rural atmosphere. Currently, the group of Dr. Chatterjee is focused on the following research topics:

•    Chemistry of atmospheric aerosols over different atmospheric environments in India
•    Behaviour of “Black and Brown Carbon” and their role in regional climate change
•    Dependence of precipitation chemistry on physical properties of rain and consequent changes on soil bio-geo-chemistry
•    Reaction mechanisms involved in various atmospheric reactions
•    Relative contributions of primary and secondary sources of atmospheric aerosols
•    Microphysical and chemical properties of low level clouds over Himalayan region
•    Biosphere-Atmosphere exchange of Greenhouse Gases and energy
•    Cloud condensation nuclei activation of atmospheric aerosols of different sizes and chemistry
•  Long-term trends in aerosols and other air pollutants in India and future prediction using suitable models: Ground and satellite based     observations
•    Sources of air pollutants and hotspots identification: small scale, local scale, regional scale, national scale and trans-boundary        
     Air pollution mitigation strategies


Dr. Sanat Kumar Das is trying to solve the fundamental problems related to Atmospheric Physics. His research group is answering the wide-ranging questions related to atmospheric sciences like (A) Air quality investigations, (B) Atmospheric measurements techniques (C) Precipitation and aerosol interactions (D) Ocean-Atmosphere interactions (E) Atmosphere-Biosphere interactions.
His research activities are involved in
•    Long-term measurements of optical, physical and chemical properties of different types of aerosols over the Himalayas
•   Simulation of Aerosol radiative effect on Earth’s radiation budget including observational data from the Himalayas to coastal using various types      of in-situ ground-based instruments and space-borne remote sensing sensors  
•    Ship-based measurements of alteration of marine aerosols mixed with continental haze and desert dust over the Bay of Bengal and Arabian Sea
•    Characterization of polar aerosols and precipitations over Antarctica
•    Alteration of aerosol hygroscopic properties in foggy environment
•    Microbial aerosols and bio-precipitation interactions
