Intercomparison Measurements of Recording Precipitation Gauges in Slovakia. World Meteorological Organization Technical Conference on Meteorological and Environmental Instruments and Methods of Observation

In order to check the accuracy and reliability of a new electronic weighing recording precipitation gauge with a very fine resolution of 0.001 mm, 99 precipitation measurements of liquid, mixed and solid precipitation were compared with the standard manually operated gauge and the heated tipping-bucket gauge. The results show that there are differences in the total amount and duration of precipitation as measured using these three types of gauges. The tipping-bucket gauge shows losses in the case of solid precipitation. In contrast, it overestimates the precipitation amounts in the case of long-duration precipitation events with moderate intensities, which is due to the repeated wetting of the buckets. After each emptying of the bucket a small amount of water remains in the bucket and is added by the following filling of the bucket to the precipitation. The more sensitive electronic weighing system can give some false records due to external influences like wind gusts
