Overview

The Aerosol-Cloud-Precipitation-Climate (ACPC) Workshop 2025 will be held on May 21-23, 2025 at the University of Tokyo in Kashiwa, Japan and online. The first half of the meeting will be devoted to shallow cloud studies, and the second half of the meeting will be devoted to deep convective cloud studies.

ACPC aims at a better scientific understanding of the interactions between aerosols, clouds, precipitation, and climate at a fundamental level. The goal is to identify, disentangle, and quantify signals of impacts of aerosol perturbations on clouds, precipitation, and radiation, considering adjustments and feedback processes by synergistically exploiting observations and models across scales.

About the ACPC initiative

The Aerosol, Cloud, Precipitation and Climate Working Group is a joint initiative of the International Geosphere–Biosphere Programme (IGBP) and the World Climate Research Programme (WCRP), developed through the cooperation of the IGBP's Integrated Land Ecosystem–Atmosphere Processes Study (iLEAPS) and International Global Atmospheric Chemistry (IGAC) and WCRP's Global Energy and Water Cycle Experiment (GEWEX).

This group meets annually to discuss progress towards research roadmaps in the sub-topics of marine low cloud systems and deep convective systems. Through these annual meetings, progress is tracked, define next steps and coordinate research activities.
