Abstract:
In order to study the influence of observation methods on precipitation measurements,several gauges and installation modes were used for experimental contrast in the atmospheric sounding testbed of CMAMOC. In this paper, we analyzed the different rain gauges and their influences of observation methods on rainfall measurements by using the experiment data,and gave the precipitation measurements of rain gauges. Result shows that the measuremens are highly relevant to gauge installation modes: the pit gauge recorded the maximum precipitation, followed by the records from the doublefence gauge,Tretyakov gauge, and normalinstallation gauge (the receiver is 70 cm above the ground). Result also shows that the current operational records by the normalinstallation gauge are slightly under the truth. Compared with rainfall measurements, snowfall measuremens are more susceptible to winds.
