Christian Klepp from the University of Hamburg

State-of-the-art satellite derived and reanalysis based precipitation climatologies still show remarkably large differences in frequency, amount, variability and temporal behavior of precipitation over the oceans. Additionally so far appropriate in-situ validation instruments were not available for shipboard usage, especially for cold season high-latitude precipitation. Provision of high quality oceanic validation data is this goal of this project that uses automated optical disdrometers that are capable of measuring liquid and solid precipitation on moving ships. Since the project start in 2009 the statistical basis for a conclusive validation has significantly improved with comprehensive data collection of more than 300.000 minutes of precipitation onboard six ships over the global oceans. The talk outlines the project goals with focus on instrumentation, algorithms, data collection and processing, quality control and validation activities.
