%X Techniques of estimating areal rainfall are firstly reviewed,and the principles of Kalman filter calibration and optimum interpolation calibration are introduced.Based on analysis of the two methods characteristics,the authors present a new method to estimate areal rainfall,i.e.,two-step calibration method.At the end,the radar data observed by the Doppler radar(CINRAD/SA) in Hefei and the raingauge data are used to evaluate the precision of the three methods.The results show that not only in precision but a...
