Role of circulation parameters in long range aerosol transport: Evidence from Winter-ICARB

► Role of circulation parameters in long range aerosol transport and distribution. ► Mechanism behind winter time elevated aerosol layers over the Bay of Bengal. ► Identification of winter time aerosol source regions and pathways into the BoB. ► Utilization of W_ICARB (first extensive campaign over the BoB during winter) data. ► Utilization of satellite and shipborne observations and NCEP reanalysis winds.
