| Abstract: | Accurate precipitation is the basis for better understanding the climate change and water cycle process. The domestic and foreign scholars have done a great deal of work for the insufficient catch rate of rain gauges. A review of recent studies on correction of errors in precipitation measurement was given in this paper. It is considered that the correction scheme for liquid precipitation is mature at present, but there is not a uniform standard for solid precipitation correction. The main reason is that the current precipitation correction schemes are lack of consideration of precipitation micro process. The full consideration of the precipitation micro process is the key to the correction of precipitation with physical significance. In addition, more detailed precipitation type determination and the record of light precipitation events are also key problems to determine the precipitation correction scheme. |
