CEOS Development Environment

Greenhouse Gas Task Team

In 2020, CEOS, with cooperation from the Coordination Group for Meteorological Satellites (CGMS) and the World Meteorological Organisation (WMO), published the Greenhouse Gas Roadmap. The CEOS-CGMS Joint Working Group on Climate (WGClimate) formed the dedicated Greenhouse Gas (GHG) Task Team in March 2019, with the primary goal to initially develop and then implement the GHG Roadmap. 

The GHG Task Team brings together experts from across CEOS and CGMS, including from WGClimate, Atmospheric Composition Virtual Constellation (AC-VC), and the Working Group on Calibration and Validation (WGCV) to help in implementing the Roadmap. In particular, Annex C outlines a number of specific actions, which is the Task Team’s primary focus for implementation. Annex C is regularly reviewed and updated to ensure the actions remain relevant.

GHG Portal

In 2023, the ESA SIT Chair Team and JAXA SIT Vice-Chair Team collaborated to develop the Greenhouse Gas Portal, which aims to provide a comprehensive and up-to-date list of all current and planned satellite missions with the ability to measure greenhouse gases. This includes those planned and operated by both public and commercial organisations, as well as NGOs. The Portal is based on data from the CEOS MIM Database and aims to support the analysis and planning of GHG measurement continuity by providing visualisation and export capabilities such as measurement timelines and tables of missions and instruments. The CEOS Database team will undertake to ensure the Portal is both comprehensive and current so that it may be applied with confidence for these studies.
