Public Review of GCOS Requirements for Essential Climate Variables
The Global Climate Observing System (GCOS) is launching an open review of the current requirements for Essential Climate Variables (ECV) that are the basis for the global systematic observation of the climate system. GCOS would like to invite as wide a possible range of reviewers to participate. This is the first step in a revision and update of the requirements planned for 2021/2.
Revisions to the existing ECV and ECV products or proposals for new ECV or ECV products can be made and support for the existing requirements is also encouraged. Comments should be submitted by end of 2017 using the on-line form at https://www.research.net/r/ECVRequirements.
Established in 1992 by WMO and other partners, GCOS maintains a list of ECV that are required to understand the climate system, to monitor changes in it and to be the basis of planning to mitigate or adapt to changes in the climate system. GCOS recognises that observation capabilities improve and the needs of users change over time. Thus, the list of ECV and their requirements must evolve as well. The current list of 54 ECVs and their individual observation requirements were published in the recent GCOS Implementation Plan and welcomed by the UNFCCC in 2016
