During the plan, it is intended to carryout extensive research in a comprehensive manner through observational, theoretical studies and modeling studies involving state-of-the-art coupled climate system models to study the sensitivity and stability of the earth system to a variety of forcings, including changes of greenhouse gases, aerosols, GHGs, solar irradiance, volcanic forcing, land characteristics, land use change etc. The various programmes will integrate the operational research and the university/academic/R & D research communities to serve as a resource to the science of climate change in the country.
