Dear members of the Cryolist,

The Global Climate Observing System (GCOS) is launching an open review 
of the current requirements for Essential Climate Variables (ECV), among 
others including Sea Ice, Glaciers, Ice Sheets and Ice Shelves, 
Permafrost, and Snow.

More details are found in the email below and in the following letter 
from GCOS: http://www.geo.uzh.ch/~mzemp/share/wgms/gcos/GCOS_ECV_Review.pdf

Make use of this opportunity to comment and further develop the existing 
GCOS ECV product requirements which have a great influence on 
requirements set by space agencies and other large programs such as the 
Copernicus services (http://www.copernicus.eu/).

Deadline: 31 December 2017

Kind regards

Michael Zemp

Dear colleague,

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 
<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[1] and welcomed by the UNFCCC in 
2016.

You can find more details in the attached document.

Kind regards,

GCOS secretariat
