The spatial correlation coefficient of the rainfall rate is an important parameter in the rain attenuation prediction method proposed by Morita and Higuti (M-H method). However, the value of this coefficient can not be used without regard to its dependence on regional differences in climate and rain type. Thus, when the M-H method is used for predicting rain attenuation, the spatial correlation coefficient of the rainfall rate determined in the relevant area should be used. The Tropical Rainfall Measuring Mission (TRMM) is a satellite project which observes the precipitation from space. Global distribution of the spatial correlation coefficient of the rainfall rate has been inferred from TRMM measurement.
