Greenhouse Gas Modelingdhanya@iiserb.ac.in +91 755 269 1379, 669 1379
The group works on utilizing atmospheric greenhouse gas observations in the inverse modelling framework in order to better understand the sources and sinks of those trace gases. This involves implementation of modelling tools at high resolution, with an emphasis on minimizing the model uncertainties. Research focus is on the Indian subcontinent, a critically important but under-sampled region.
Monsoon Dynamics, Climate and Glacier Modelingkumarp@iiserb.ac.in +91 755 269 1385, 669 1385
The group is involved in improving the understanding of climate variability and change using a regional earth-system model. Presently working on monsoon dynamics, air-sea interactions, glacier mass-balance studies, tropical cyclones using 40-var data assimilation technique, drought dynamics, observation and model uncertainties. Also actively involved in capacity development and providing adaptation strategies to different stakeholders for global and regional change
Aerosol Physics and Chemistry, Receptor Modelsramyaasr@iiserb.ac.in +91 755 269 1371, 669 1371
The group works on air quality management and assessment of aerosol induced climate effects, in order to provide scientific inputs for policy making. Receptor modelling in conjunction with air-parcel trajectory ensembles is used to identify source-receptor relationships and source locations of airborne pollutants. The group also works on understanding atmospheric physico-chemical transformations of aerosols and their relationships with gaseous co-pollutants.
