- Abstract
The utilization of satellite based and reanalysis climatic data has significantly advanced in hydro meteorological research in regions with limited observations. Before implementing satellite based and reanalysis-based data in specific locations, it is crucial to thoroughly assess their accuracy. This study focused on evaluating the accuracy of reanalysis climate data and Tropical Rainfall Measuring Mission (TRMM) satellite rainfall data compared to observed climate data in different agro climatic zones of Tamil Nadu, India. The evaluation was conducted on a monthly basis from 1981 to 2017. Furthermore, the performance of the precipitation product obtained from Tropical Rainfall Measuring Mission was also evaluated with reanalysis data at weekly basis from 1998 to 2017. Various statistical methods such as bias, root mean square error, index of agreement, and refined index of agreement were employed for this assessment. The results show that, the reanalysis and observed monthly data for rainfall, maximum and minimum temperature show a strong correlation in all zones of Tamil Nadu, except for the High rainfall and Hilly zone. TRMM rainfall values effectively capture rainfall data, but satellite data can overestimate and underestimate rainfall amounts, as revealed by the validation of satellite and reanalysis precipitation data.
