I am working on modelling of atmospheric aerosol properties and the impact of aerosols on climate change.

Objectives

• Estimation of spatially and temporally resolved observation-constrained emissions of black carbon (BC), organic matter (OM) and sulfur di-oxide (SO2) over the Indian region with a strategic integrated modeling approach.
• Evaluation of wintertime direct radiative effect due to BC aerosols over Indo-Gangetic Plain (IGP) as modelled with new BC emission inventories in chemical transport model, CHIMERE.
• Estimation of population exposure and potential risk due to wintertime BC pollution load simulated with constrained BC emission in CHIMERE and mitigation compared to that using the baseline BC emission (low emission scenario).
• Characterization of the seasonality in radiative effect simulated with improved BC emission over the Indian subcontinent.

Importance

My research works are focused on improvement of emission database over Indian domain, estimation of direct radiative effect and health impact due to BC during winter. I also developed a sustainable mitigation plan to reduce the BC emission.
