Panels

Three scientific panels, reporting to the Steering Committee, were established to define the observations needed in each of the main global domains (atmosphere, oceans and land), to prepare specific programme elements and to make recommendations for implementation:
•    Atmospheric Observation Panel for Climate (AOPC)
•    Ocean Observations Physics and Climate Panel (OOPC)
•    Terrestrial Observation Panel for Climate (TOPC)

The scientific panels gather experts in the respective areas to generate inputs from these fields to the climate observing community.
 

The Terms of Reference for GCOS Panels were revised by GCOS SC-30 (Decision 30/7) and they came into force in 2023. Below, the section specifying the composition and terms for Panel members and chairs, common to the three panels, is presented. Specific terms to each of the panels (specifying their activities and so on) can be found under the AOPC, OOPC and TOPC webpages.
