Aerosol chemistry


  • 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
