A ship rain gauge for use in high wind speeds

Abstract

A ship rain gauge has been developed that can be used under high wind speeds such as those experienced bv ships at sea. The instrument has an improved aerodynamic design and an additional lateral collecting surface, which is effective especially with high wind speeds. The ship rain gauge has been calibrated at sea against a specially designed optical disdrometer. An accuracy of 2%-3% has been obtained for 6 hourly sums. The ship rain gauge has also successfully been tested at a test site of the German Weather Service and presently is used on research vessels and voluntary observing ship.
