The CCCR’s Earth System Model Development team has developed an Earth System Model (IITM-ESM) to address the long-term critical need in India for a climate model that would provide reliable future projections of monsoon rainfall.
The Climate Change Science and Applications group in CCCR has generated an ensemble of high resolution downscaled projections of regional climate and monsoon until 2100 for the IPCC climate scenarios, which are useful for climate impact assessment studies and for quantifying uncertainties in the regional projections.
The Atmospheric Chemistry and Climate research in CCCR focus on understanding the role of trace gases and aerosol chemistry in radiative forcing and regional climate change, and to quantify the impact of trace gases transported from the boundary layer to the Upper Troposphere and Lower Stratosphere (UTLS).
The CCCR’s Paleoclimate group has documented features of past monsoon climatic variations based on climate reconstructions derived from high resolution proxies through dendroclimate studies, stable isotope analysis of climate archives (e.g., tree rings, corals, speleothems etc).
The MetFlux India team in CCCR monitor green house gases (GHG) concentration variations over Indian region by in situ measurements and generate observations of GHG fluxes over a network of Indian stations covering different ecosystems and identify the sources and sinks of GHG.
