摘　　要：Composite microwave index (CMI) method is used with the satellite SSM/I data to retrieve summer rainfall rate over 96°E-127°E, 17°N-44°N. The results of verification are : the root_of_mean_square error is 0.9 mm/h in the actual rain rate range from 2 to 2.9 mm/h; 1.6 mm/h in that from 3 to 5 mm/h and the maximum rms error is 4.2 mm/h in that from 5.1 to 50 mm/h. Case study shows the decision tree and CMI method presented in the note are effective to the rainfall recognition and rain rate retrieval over land of East China.Composite microwave index (CMI) method is used with the satellite SSM/I data to retrieve summer rainfall rate over 96°E–127°E, 17°N–44°N.
