GCOS invites all interested experts, from those making observations to those using the climate data, to review the new GCOS Implementation Plan. This report aims to guide the development and improvement of the global climate observing system. It is the latest in a series of similar plans produced every 5-6 years and will be presented to the UNFCCC later this year at COP 27 in Sharm el-Sheikh, Egypt.
The report builds on the 2021 GCOS Status Report that reviewed the state of observations of the climate identifying gaps and issues. The Implementation Plan is presented in a clearer way compared to earlier reports: it describes activities that need to be undertaken in the next 5-10 years to improve the observing system with clear linkages to desired outcomes. It also includes revised observing system requirements of all the Essential Climate Variables (ECVs) which prove more detail than was available in the past.
Following this review all the comments will be examined by the GCOS expert panels and writing team before a final version is approved by the GCOS Steering Committee for submission to the UNFCCC, WMO and IOC.
The review opened on Monday 2nd May 2022 and closed on Friday 3rd June 2022.
