Abstract: Short term rainfall climatology studies are essential for disaster management and planning in hilly areas. Uttarakhand State, India is prone to cloud burst and flooding events like one occurred at Kedarnath region in June 2013. Rain gauge stations are scarce and rainfall monitoring is difficult over this region due to rough terrain and extreme environmental conditions. Therefore, the available rainfall data is inconsistent with large historical gaps. Remote sensing based Tropical Rainfall Measuring Mission (TRMM) provides reliable site specific rainfall information. This study aims in calibrating and validating TRMM 3B43V7 derived seasonal precipitation data with rain gauge derived measurements over the period 1998- 2012. Geographical information system and statistical indices viz. Correlation Coefficient (r), Mean Square Error (MSE) and Root Mean Square Error (RMSE) are used for analysis. Results revealed good agreement (r=0.92) between TRMM and rain gauge measurements for Haridwar station with slight underestimation during rainy season. ¬© 2016 IEEE.
