Abstract

Real-time meteorological products derived from INSAT-3D and INSAT-3DR satellites are very important in operational weather forecasting due to their larger spatial coverage and consistent availability. However, validation of the satellite-derived products is an essential step in ensuring accuracy and reliability of the products for integration in any specific application. The validation process involves comparing spatially and temporally co-located data obtained from satellites with ground-based observations as well as other sources of information to identify any discrepancy or error. In this paper, validation results of INSAT-3D/3DR satellite-derived meteorological products have been briefly discussed. Meteorological products derived from imagers and sounders onboard both satellites showed comparable error characteristics. As imager and sounder instruments of the upcoming INSAT-3DS satellite will have the same technical specification as INSAT-3D and INSAT-3DR satellites, these validation results will be helpful to improve the accuracy of geophysical products derived from INSAT-3DS satellite through fine-tuning of the existing algorithms.
