An introduction is made to the observational experiments on solid precipitation at the Changchun station of Jilin Province, Tonghe station of Heilongjiang Province, and Daxigou station of Xinjiang Province from January to September in 2006. There are three types of sounding apparatuses (21 in total) from six manufacturers participated in the 9month experiment. The experiments used the Double Fence Intercomparison Reference (DFIR) recommended by WMO (1985) as the standards. Through the experiments, the characteristics of tippingbucket gauges, weighingrecording gauges, laser precipitation monitors in measuring different type precipitation were tested, which provide a basis for the selection of the automatized observational equipment on solid precipitation and the operational service promotion of solid precipitation.
