Pune: Indian Institute of Tropical Meteorology (IITM), Pune, will be working on its first climate change model. So far India has been using the climate change data from international models, however, this new model will help scientists in the country to analyse the impact of climate change with the data and different parameters used exclusively for India.
Speaking to Sakal Times, Ravi S Nanjundiah, Director, IITM Pune, said that for climate change so far India has been using international models.
“We did not have any model for India-specific readings. However, with our own Earth System Model and an inter-comparison project with other global models, we will be able to analyse climate change with respect to that of India. So far we needed to borrow the data from global models but now with our own model in place we will be able to project the exact impact of climate change in a better way,” said Nanjundiah.
Earth System Models (ESM) are important tools that help understand and quantify the physical, chemical and biological mechanisms governing the rates of change of elements of the earth systems which comprise the atmosphere, ocean, land, cryosphere and biosphere.
He said stimulation of the model is undergoing and by the end of 2018, all the data will be collected. “This data will be analysed till mid-2019,” said Nanjundiah.
He said the existing ‘Monsoon mission’ models were modified to get an earth system which will help analyse climate change.
“The data required to analyse the climate change is that of past 100 years and so needed to make some modification to the system we had. So the new system which is an earth system will yield results highlighting the climate change,” said Nanjundiah.
