Abstract

Rain is one of the most crucial elements in any climates. Knowing the methods of estimating rainfall can have be a very important role in understanding and predicting climate system. The old ways of measuring precipitation, is usually based on climatology stations, synoptic and rain gauge. In the recent years, new methods, based on the technology of measuring, have been used by specialists, to measure the precise amount of rainfall and other climatic factors through satellites and meteorological radars (Robinso and Kulielt, 2000) .TRMM is the first satellite that can measure the precipitation rate and distribution, using a combination of microwave and radar sensors. In studies such as Sharma (2003) and Prakash and Gairola (2013) in India, and Zang et al. (2011) in China, analysis has shown, a high correlation between satellite data and ground. In this study also, for the Spatial-Temporal evaluation of rainfall data from TRMM satellite radar was used, and was compared Satellite data of climate stations, in Khorasan Razavi Province.
