Global Climate Observing System
Dr Stephan Bojinski, GCOS Secretariat
CBS/GCOS Expert Meeting on GSN and GUAN, Asheville, USA
The GCOS Mission
To ensure that the data required to meet the needs of users for
climate information are obtained and made available for:
• Climate system monitoring, climate change detection and
attribution;
• Research to improve understanding, modelling and prediction
of the climate system;
• Assessing impacts of, and vulnerability to, climate variability
and change, e.g. extreme events, sea-level change, inputs for
adaptation analyses;
• Application to sustainable economic development.
Global, long-term, high-quality, sustainable, reliable, …
GCOS Strategy
 Identify observational requirements for climate applications

Science panels (AOPC, OOPC, TOPC), partners, sponsors

Identify networks/systems needed to meet requirements
 Build on existing systems to the extent possible

Work with partners to implement systems to GCOS standards;
other observing systems, sponsors, CEOS, IGOS, GEOSS…
 Engage intergovernmental, regional and national bodies

UNFCCC/COP on ‘systematic observation’ requirements

National and regional entities to address deficiencies

Capacity building
 Resource mobilization

Multi-governmental funding, national support

GCOS Cooperation Mechanism
GCOS is comprised of climate components of various global observing
systems including both satellite and in situ observations

Second Adequacy Report to UNFCCC (2AR)
 Requested by SBSTA-15 (Marrakech, Nov. 2001) to:

Determine progress since the First Adequacy Report (1998);
 Determine the degree to which current networks/systems meet
scientific requirements and observing principles;
 Assess how well current and planned systems meet the needs
of the Convention.
 Identified 44 ‘Essential Climate Variables’ (ECVs) that are
both currently feasible for global implementation and have
high impact on UNFCCC requirements.
 Endorsed by WMO Cg-XIV and SBSTA-19/COP-9 (Dec. 2003)
Essential Climate Variables
 Atmospheric (16)
• Surface – Air temperature, Precipitation, Air pressure, Surface radiation
budget, Wind speed and direction, Water vapour
• Upper Air – Earth radiation budget (including solar irradiance), Upper-air
temperature (including MSU radiances), Wind speed and direction, Water
vapour, Cloud properties
• Composition – Carbon dioxide, Methane, Ozone, Other long-lived
greenhouse gases, Aerosol properties.
 Oceanic (15)
• Surface – Sea-surface temperature, Sea-surface salinity, Sea level, Sea
state, Sea ice, Current, Ocean colour (for biological activity), Carbon
dioxide partial pressure
• Sub-surface – Temperature, Salinity, Current, Nutrients, Carbon, Ocean
tracers, Phytoplankton
 Terrestrial (13)
• River discharge, Water use, Ground water, Lake levels, Snow cover,
Glaciers and ice caps, Permafrost and seasonally-frozen ground, Albedo,
Land cover (including vegetation type), Fraction of absorbed
photosynthetically active radiation (FAPAR), Leaf area index (LAI),
Biomass, Fire disturbance.
GCOS Implementation Plan
 The Plan (requested by Decision 11/CP.9, UNFCCC COP-9, 2003):

Draws on expressed views of Parties with respect to 2AR

Takes account of existing global, regional and national plans and
programmes, including IGOS, GMES, and GEO

Based on extensive consultations with a broad range of scientists and
data users, including open review before completion

Includes indicators for measuring implementation

Identifies implementation priorities and resource requirements
 Recommends that Parties (i.e., countries):

Need, both individually and collectively, to commit to the full
implementation of the global observing system for climate, sustained
on the basis of a mix of high-quality satellite measurements, groundbased and airborne in situ and remote-sensing measurements,
dedicated analysis infrastructure, and targeted capacity-building.
UNFCCC COP/SBSTA Buenos Aires 2004
Decision 5/CP.10 and SBSTA-21 Conclusions
 Welcomed the Plan
 Encouraged Parties to strengthen their efforts to address the
priorities identified in the Implementation Plan,

incorporate actions in their national plans and report on their
activities.
 Welcomed the emphasis on enhancing the participation of
developing countries and encouraged Parties to implement
“regional action plans”
 Appreciated the collaboration between GCOS and GEO.

Welcomed progress on 10-year GEOSS implementation plan

Incorporate actions in GCOS IP into the GEOSS IP.
 Invited Parties supporting Earth observation satellites to provide
a coordinated response to IP actions.
 Invited GCOS to report on progress at subsequent sessions.
Priority Areas in Implementation Plan

131 Actions to implement Essential Climate Variables
(ECVs) globally

Priority over the first 5 years :
1. Improving access to high-quality global data for the essential
climate variables (ECVs);
 Free and unrestricted data exchange
 Adherence to the GCOS Climate Monitoring Principles for in situ
and satellite systems
 Availability of international data centres
2. Generating integrated global analysis products;
3. Improving key satellite and in situ networks;
4. Strengthening national and international infrastructure;
5. Enhancing of the full participation of least-developed
countries and small island developing states.
Characteristics of the Plan
 Estimated costs about $630 M/year
 A major satellite component, operated in a manner that ensures the
long-term accuracy and homogeneity of the data. [Satellites ~41% of
costs]
 Some ECVs will remain critically dependent on in situ
observations for full measurement or for calibration and validation of
satellite records. [In situ networks ~38% of costs]
 Global participation is essential for global coverage of key in-situ
networks. [Capacity building ~5% of costs]
 Sustained product generation and improved data management.
[Infrastructure ~10% of costs]
 International oversight and coordination – linkage to GEO.
[Oversight of implementation ~4% of costs]
