Precipitation measurement over the global oceans onboard moving ships is a notoriously difficult task. Gauge based systems are prone to large undercatch errors due to fluctuating high wind speeds and flow distortion. While the errors are large for rainfall, the estimation of snowfall and mixed-phase precipitation is impossible. In addition to the precipitation accumulation, precise information about the particle size distributions for rain and snow are required for various tasks, e.g. calibrating spaceborne radars or to improve understanding of the microphysical properties of precipitation. Thus, systematic high quality oceanic in-situ precipitation measurements are requested on an international science level and are essential for improved understanding and validation of hydrological processes in satellite, re-analysis and model data.
The automated optical disdrometer systems (ODM470) is capable of measuring precipitation occurrence, intensity and accumulation through minute-based particle size distributions discriminated for rain, snow and mixed-phase precipitation. The ODM470 was especially designed for shipboard operation under high and frequently varying wind speeds, flow distortion conditions and rough sea states.
