Evian, France (ABC Live) : The 53rd Plenary Session of the Coordination Group for Meteorological Satellites (CGMS) took place from 2 to 5 June 2025 in Evian. Representatives from the World Meteorological Organization (WMO), its Global Greenhouse Gas Watch (G3W) initiative, and major space agencies gathered to discuss the future. Their goal was to advance global Earth observation (EO) in a climate-critical, data-driven era.
A Transforming Earth Observation Ecosystem
The EO landscape is changing fast. Both public and private sectors are becoming more involved. Moreover, AI-powered tools and data-rich satellite missions are reshaping data collection and use. Consequently, CGMS remains central by coordinating meteorological satellite programs. These programs support weather prediction, climate modeling, and disaster preparedness worldwide.
Strengthening Data Cohesion and Accessibility
A key focus was integrating private-sector satellite data. At the same time, maintaining interoperability standards is essential. Therefore, the WMO reinforced its commitment to the Unified Data Policy. This policy promotes open access to satellite data as a global public good. This access is especially important for least-developed countries that rely on timely, free information.
In addition, the plenary reviewed initiatives like the WMO Information System (WIS 2.0) and the WMO Integrated Global Observing System (WIGOS). These efforts aim to modernize data infrastructures. Furthermore, they ensure climate data is discoverable and usable worldwide in real time.
Progress on G3W and Satellite Missions
The G3W Implementation Plan is gaining strong support from space agencies. Recently, several satellite missions have been launched or are planned, including:
-
FY-3 and TANSAT-2 by China Meteorological Administration (CMA)
-
CO2M satellites under ESA’s Copernicus program
These missions align with the CEOS/CGMS Greenhouse Gas Roadmap. As a result, they will improve the resolution and frequency of greenhouse gas monitoring globally.
Building a Resilient Future
WMO Deputy Secretary-General Ko Barrett said, “powerful Earth observation is about the quality, quantity, and diversity of the data.” As Meteorological Satellites (CGMS) become smarter and more autonomous, they will provide more reliable real-time data. This data is critical for early warnings, emissions tracking, and climate adaptation.
Conclusion: Collaboration, Innovation, and Inclusive Access
Overall, the CGMS-53 plenary reaffirmed global commitment to transparent and interoperable Earth observation. Moving forward, as the world embraces more actionable satellite data, next-generation Meteorological Satellites will be key. Together, they will help build a climate-resilient future that includes all nations.
