Short summary

Aircraft-based measurements of vertical profiles of aerosol properties, across the Indo-Gangetic Plain (IGP), prior to onset of the Indian summer monsoon reveal a highly absorbing aerosol system over the IGP. Aerosols over the west IGP are mostly natural, larger in size and scatter light efficiently. Those over the central and eastern IGP are mostly anthropogenic in origin, smaller in size and absorb more light. Elevated absorbing aerosol layers may modulate regional precipitation patterns.
