Working Group 2 - Data Development

Vision

To advance understanding of the four key precipitation processes ― ARs, Monsoons, TCs, and MCSs ― by transforming the accessibility, quality, and usability of precipitation data, especially in data-sparse regions. These efforts aim to provide the observational bedrock that underpins improved precipitation prediction and climate modelling, contributing to long-term climate understanding and societal resilience.

Objectives/Mission

WG2 aims to improve understanding of the four key precipitation processes by integrating rain gauge, radar, snow weight, satellite, reanalysis, and other precipitation-relevant data into robust, high-quality observational datasets.
