| Abstract |
INSAT multispectral Rainfall Algorithm Technique (IMSRA) is one of the main operational rainfall retrieval algorithms for INSAT-3DR. This algorithm estimates precipitation based on non-linear power law relationship established between infrared (IR) brightness temperatures (Tbs, 10.7 µm observations) and TRMM-PR surface rain rate. Based on a number of case studies and research works carried out, a further refinement of the algorithm was made. |
| Info |
A correction scheme is designed for IMSRA algorithm. The modified algorithm takes two consecutive IR images as input. The Procedure adopts a global and regional bias correction of rain followed by cloud growth/decay correction. After the corrections, IMSRA based half-hourly rain estimates are generated at pixel resolution (~4 Km). |
