New Delhi , Mar 11: India has planned to launch an advanced satellite, INSAT-3D dedicated to weather forecasting by the end of this year. The satellite will have six channel imager and 19 channel sounder.

“This satellite will be almost similar to GOES satellites of US. The INSAT-3D data shall provide necessary quantitative products in addition to earth imagery in six channels need for making quality weather forecast,” said the the secretary in the ministry of earth sciences, PS Goel.

The new advanced satellite would provide vertical profiles of temperature and humidity, atmospheric motion vectors, outgoing longwave radiation, quantitative precipitation estimates, sea surface temperature, Himalayan snow cover, snow depth, data on fire, smoke and aerosol. It will also monitor upper troposphere humidity, ozone layer, fog, vegetation index, flash flood.

“All these data will be used in weather forecasting by conventional methods and most of it would be assimilated in numerical weather prediction models to achieve greater accuracy. Indian Space Research Organisation is also planning to launch Oceansat-II and Meghatropique Low Earth Orbiting (LEO) satellites,” he said.
