In the last 10-12 years the scientists have familiarized with the various GCM's and AGCMS with specific emphasis on Indian monsoon and model simulations. The initial experiments were based on the specific events and model simulations to understand the climate forcing.

In the Palaeo climate change Proxy analysis, ISRO studies are perhaps the only few quantitative studies made using the deep sea sediments and near coast sediment cores through coarse and fine resolution analysis. The initial observations would date up to 40,000 yrs BP and 10,000 yrs BP respectively and provided some clues on the past climate and monsoons over the Indian region. The other Proxy indicator studies on spleo-therms, corals, tree rings and pollen etc. is also being investigated on project basis.

NEW THRUST:

The implementation of Regional climate Modeling (RCM) over the Indian climate region with the 30KM x 30km grid resolution (initially and later up to 10KM) and assimilating the boundary conditions derived from the satellite data is proposed for the first time. The model is proposed to simulate the weather conditions 100 days in advance before the SW and NE monsoons with the possibility to run several ensembles to confirm the model simulations.
