I am working on modelling of atmospheric aerosol properties and the impact of aerosols on climate change.
Objectives
PhD Thesis Title:
Radiative perturbation and health impact due to black carbon aerosols over the Indian subcontinent
Objectives:
1. Estimation of spatially and temporally resolved constrained emissions of BC, OM and SO2 over the Indian region with a strategic integrated modelling approach.
2. Evaluation of wintertime radiative perturbation due to BC aerosols over the IGP as modelled with new BC emission inventories in a chemical transport model.
3. Evaluating the inter-seasonal spatial changes in the atmospheric BC burden and radiative perturbation over India.
4. Estimating the BC health impact in the IGP: Exposures, risks, and mitigation.
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.
