Outline
• Summary of 1st meeting of Joint CEOS-CGMS
Working Group on Climate (WGClimate)
– Full meeting www.ceos.org=>climate=>meetings
• Ideas on mapping between ECVs and WCRP
science priorities

Summary of 1st meeting of Joint CEOS-CGMS
Working Group on Climate (WGClimate)
• WGClimate was pleased that only minor updates to the original
Terms of Reference were needed to accommodate inclusion of the
Coordination Group for Meteorological Satellites (CGMS)
• CGMS approve the Terms of Reference at their Plenary in July 2013
and CEOS at their Plenary in November 2013
• A new overarching objectives statement was added:
•
•
•
Provision of a structured, comprehensive and accessible view as to
what Climate Data Records are currently available from satellite
missions of CEOS and CGMS members or their combination;
Creation of the conditions for delivering further Climate Data Records,
including multi-mission Climate Date Records, through best use of
available data to fulfil GCOS requirements (e.g. by identifying and
targeting cross-calibration or re-processing gaps/shortfalls );
Optimization of the planning of future satellite missions and
constellations to expand existing and planned Climate Data Records,
both in terms of coverage and record length, and to address possible
gaps with respect to GCOS requirements

Climate Monitoring Architecture
• The WGClimate ‘Strategy Towards…’ report primarily
focused on the first 2 pillars of the Climate Monitoring
Architecture and its logical, or generic, view.
• WGClimate will be focusing on identifying case
studies and working with the GFCS to focus on the
applications and decision-making pillars.
• A third phase will then identify several example
physical architectures that incorporate the end-to-end
climate information value chain

Assessing the Completeness of ECVs
• Metrics to assess the completeness of process (documentation,
validation, access, etc.) and scientific applications (fitness for
purpose and user requirements) have moved forward within several
different venues over the last year
• WGClimate has coordinated with the GEO QA4EO effort
• An EU project, CORE-CLIMAX, has proposed a more generic
metric assessment that has been evaluated and found useful by
the satellite, in situ, and re-analysis communities
• WGClimate took an action to have its members further
evaluate this metric for formal adoption by WGClimate by
the end of 2014
• WGClimate is coordinating with WCRP Data Advisory
Committee on scientific assessment metrics. Work is ongoing

Mapping ECVs to WCRP Science Priorities
• CEOS-CGMS WGClimate is committed to addressing
GCOS Implementation Plan and related documents
(e.g., Satellite supplement, guidelines, etc.)
• GCOS has gathered requirements for ECVs that focus
on large-scale decadal trends for groups of climate data
records
• This approach does not always map well into WCRP
science objectives
• Other GCOS actions and guidelines (e.g., data
processing, metrics) do apply to WCRP, however, are
not formally recognized and implemented by WCRP

Mapping ECVs to Fluxes
• In important first step is to identify priority
science and map ECVs required
• ECVs can also be given priorities for their
impact on flux calculations
• Check ECV requirements with science
requirements for the ECV and identify gaps
• Identify any gaps in ECV list that are required
for science and provide requirements for
consideration to GCOS
3rd WCRP Data Advisory Committee
Summary and Recommendations
• CEOS-CGMS Joint Working Group on Climate was
approved and held its first meeting
– WDAC should have only 1 report from CEOS-CGMS
Joint WGClimate Chair
• WGClimate is pursuing adopting metrics for
process by later this year
– CORE-CLIMAX update to Maturity Model
• WDAC should identify which fluxes to prioritize
and explore a mapping to ECVs to engage
WGClimate ongoing work
