Aerosol chemistry

RESEARCH ACTIVITIES

• Chemical characterisation of atmospheric aerosols at geographically distinct environments over Indian region
• Studies on size-resolved chemical composition
• Characterisation of organic aerosols Assessment of the anthropogenic influence
• Use of Chemical composition for identification of sources & transport processes (as tracers)
• Development of Chemical Models of aerosols for geographically distinct regions over Indian subcontinent to form inputs to radiative transfer/climate models
