The raindrop size distribution is a crucial information for atmospheric sciences, remote sensing and communications. Its current observations (from disdrometers) are rather spread between countries and institutions with heterogeneous variables and formats, hampering easy and broad access to public analysis-ready data sets. DISDRODB is an infrastructure (with associated softwares) aiming to provide a unified framework for the systematic sharing, standardization, and processing of disdrometer data. I will introduce DISDRODB and discuss the challenges to develop such tools.
