Angshuman Modak

Assistant Professor

My work focuses on understanding how Earth’s climate system responds to various perturbations ranging from natural phenomena to human activities, across global and regional scales, such as India, South-East Asia, the Tropics, and the Arctic.

PhD

The aim of my research is to improve our understanding of the role of Aerosol Cloud Interaction (ACI) in modulating climate dynamics. The focus is to analyse the spatiotemporal variability of ACI forcing & associated climate response primarily using climate models. The findings will address key uncertainties in climate response surrounding ACI which will e..
