"Global Change Observation Mission (GCOM)" is an international plan of Japan Aerospace Exploration Agency (JAXA). GCOM seeks to establish and demonstrate a global, long-term satellite observing system to measure essential geophysical parameters for understanding the global climate change and water cycle mechanism, and eventually contribute to improving future climate projection through a collaborative framework with climate model institutions.

To achieve global, comprehensive, long-term, and homogeneous observation, GCOM will consist of two satellite types and three consecutive generations with a one-year overlap, resulting in over a 13-year observation period. The two satellites are GCOM-W and GCOM-C (Climate). The GCOM-W1 satellite will carry the Advanced Microwave Scanning Radiometer-2 (AMSR2) to contribute to understanding the water and energy cycle. The GCOM-C1 satellite will be equipped with the Second-generation Global Imager (SGLI) to observe the Earth’s atmosphere and surface for contributing to the understanding of the carbon cycle and radiation budget.

At this symposium, JAXA and the organizations concerned report a background, a purpose, and a role of the GCOM plan, and the present status of the climate change research by the satellite observation. JAXA holds this symposium so that participants can understand the GCOM plan and the global environment issues.
