Signatures of aerosol-induced decline in evapotranspiration over the Indo-Gangetic Plain during the recent decades

Evapotranspiration (ET) is the primary process of water transfer in hydrological cycle over land and linked to water, energy carbon cycles. While global expected intensify a warming climate with enhanced ET precipitation, magnitude spatial distribution regional scale response change remains uncertain. Here we present an analysis in-situ observations from 23 stations India during 1979-2008, which shows that annual has declined by about 9% humid sub-regions Indo-Gangetic Plain (IGP). Additional high-resolution model simulations observed datasets lend support role aerosol-induced solar-dimming intensifying reductions, background decreasing monsoon precipitation soil-moisture levels, IGP
