Typical pattern in winter-specific aerosol loading over middle-IGP was recognized.
Intra-seasonal variation in MODIS-AOD and FMF was consistent with source strengths.
At higher altitude accumulation of dusts were linked to trans-boundary origin.
At lower altitude continental westerly accumulates smoke from upper to middle-IGP.
Cooling at SUF & TOA and warming at ATM leading to high heating rates.
