The GCOS Second Report on the Adequacy of the
Global Observing System - April 2003

Authors: GCOS, in collaboration with the Global Terrestrial Observing
System (GTOS), the World Weather Watch (WWW) with its Global
Observing System (GOS) and the Global Atmosphere Watch (GAW).
Scope: international, regional, national and individual activities to be
coordonated internationally
Aim of the report: report on the adequacy of the global observing systems
for climate; establishing the scientific requirements for systematic climate
observations.
The goals of this Report were to determine what progress has been made
in implementing climate observing networks and systems since the first
report; determine the degree to which these networks meet with scientific
requirements and conform with associated observing principles; and assess
how well these current systems, together with new and emerging methods
of observation, will meet the needs of the UNFCCC.
Annex lists key climate variables and describes systems (available and
potential)
GCOS Implementation Oct 2004
• Exact same Climate Variables as 2nd adequacy report
– Assigned priorities, and specified actions
• Criteria to assign current or near future priority:
– Significant and citable benefits towards meeting…….blah blah… in
support of impact assessment, prediction and attribution of climate
change and the amelioration and/or adaptation.
– Feasibility of an observation availability of acceptable accuracy and
resolution in time and space.
– Tractable set of implementing actions
– Cost effective
• Lists specific ‘Actions’ for example:
Maintain current glacier obsv. sites, add more in S. America, Africa,
Himalayas & NZ
Who: Parties national agencies coordinated by GTN-G WGMS, USGS &
IGOS-P Cryo.
‘Obtain integrated analysis of snow cover over both hemisphersw.
Who: Space agencies thru CliC & IGO-P cryo……
CEOS response to GCOS
implementation
”CEOS identifies what can be achieved by better coordination of
existing and future capabilities as well as those improvements that
require additional resources and/or mandates beyond the present
capacity of space agencies. This report is intended to initiate action
and assist the Parties in advising and commenting on the planning
actions within the agencies.”
Specifically respond to actions in the implementation plan. For
example
Action O-2: Relevant CEOS space agencies will consult with
the science community on appropriate retrieval algorithms of
passive microwave observation for reprocessing sea ice products

• Listed for special data archaeology efforts
– Sea Ice Extent, NSIDC
– Extent and mass balance of glacial extent and
mass balance of mt. glaciers, WGMS
Arctic Planning/IPY
ICARP Working Group 7 report on cryospheric and hydrological
processes and systems.
Community document written for research planning purposes.
Focuses on Arctic terrestrial, Coordinate large number of relatively
independent projects. Data monitoring recommends super sites
(CEOP?) and roving sites. Snow, recommend glacier inventory
(GLIMS/surface area), mass balance of selected glaciers and
Greenland.
Toward an Integrated Arctic Observing Network, from the National
Research Council
No specific recommendations, cryosphere not addressed explicitly.
Still at the idea stage.
AOSB-CliC Observing Plan for the International Polar Year IPY
proposal for Arctic Ocean Observing System. iAOOS. What is
described is a plan not necessarily the plan. Nice diagrams of
observing system.
EuroGOOS Arctic Task Team Planning Document Focused on
ocean, not many specifics still at ideas stage.
Terrestrial • EnviSnow user requirements document Limited region,
implementation plan for producing specific snow
products.
– Limited region (Nordic, Austria mountain regions)
– Example of the wide variation of requirements based on user
surveys.
– EUMETSAT Satellite Application Facilities hydrology report,
including requirements for snow
• EUMETSAT Satellite Application Facilities hydrology
report, including requirements for snow
– Motivated by flooding, European focus.

A white paper on a global cryosphere climate monitoring system
Not focused on observations but more on retrieving cryospheric data for
users & on providing algorithms. Report originally written as a proposal for a
climate monitoring system and service for development within ESA’s GMES
Service Element (GSE); but not supported.
