While a significant part of the work and structure of GCOS is organized around its three main components—atmosphere, ocean, and land—GCOS outputs are designed to provide a comprehensive, cross-domain perspective on climate observation. To achieve this, joint panel meetings are held periodically, offering opportunities for experts from diverse disciplines to interact, build a shared understanding of key topics, and collaborate toward common goals. The 2023 Joint Panel Meeting was particularly instrumental in laying the groundwork for implementing the recommendations outlined in the 2022 GCOS Implementation Plan.
