Global Climate Observing System
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, modelling and prediction of the climate system;
Assessing impacts, vulnerability & adaptation;
Application to sustainable economic development.
Global, long-term, high-quality, sustainable, reliable, …
GCOS is comprised of climate components of various global observing
systems including both satellite and in situ observations

Recent GCOS Actions on
GAW Ozone Networks


GCOS Steering Committee (October 2007) recognized:

GCOS Global Baseline Total Ozone Monitoring Network

GCOS Global Baseline Ozone Profile Network
Atmospheric Observation Panel for Climate (AOPC, April
2007):
 Recognized high data reception rates for GAW ozone
networks
 Recommended one-stop point for submission and
access to data
GCOS Implementation Plan (2004)

Responds to UNFCCC request to develop an
implementation plan that considers:


Requirements in the ‘Second Adequacy Report’;

Essential Climate Variables (ECVs)

Integrated global analysis products

Views of Parties with respect to that report;

Existing global, regional and national plans;

Open review by broad range of scientists and data users;

Indicators for measuring implementation;

Implementation priorities and resource requirements.
Identified as the Climate component of the Global
Earth Observing System of Systems (GEOSS)
Ensuring the Satellite Climate Record
• Scientific Requirement Definition
– Preparation of GCOS “Satellite Supplement”
(2006)
– Ongoing Scientific Interaction
• Satellite Agency Coordination
– Committee on Earth Observation Satellites
• Formal CEOS response to UNFCCC
– Coordination Group for Meteorological
Satellites
• Objective: Stable, Calibrated Satellitebased Climate Products
– An interruption in a national satellite
contribution should not mean a failure
in the Climate Record
UN Framework Convention on Climate Change
GCOS-Related Actions - 2007
 Adopted the revised UNFCCC reporting guidelines on global
climate observing systems
 Invited Parties to submit to GCOS Secretariat “additional
information” on observing systems by 15 Sept. 2008, using these
guidelines
 Requested CEOS report on satellite observations for climate in
December 2009
 Urged Parties implement GCOS Regional Action Plans
 Requested comprehensive report on GCOS
implementation in June 2009 (restated)

Rationale
 Motivation
•
Problems for climate in accuracy, long-term stability
•
Changes in measurement systems
 Objectives
•
Provide long-term, high-quality climate records
•
Constrain/calibrate data from more spatiallycomprehensive global observing systems (including
satellites)
•
Measure large suite of co-related climate
variables

Lindenberg Report to be released; Invitations to stations
Proposed Site Instrumentation
Level 1 (Highest Priority) Measurements

Standard surface variables (pressure, temperature, humidity and
wind)

Redundant / simultaneous measurement of temperature and water
vapor

Pressure and GPS / radar height

Ground-based GPS receivers (column water vapor)
Level 2 Measurements

Surface radiation (BSRN suite)

Microwave radiometer (temperature/moisture profile)

Multi-channel infrared radiometer (such as AERI;
temperature and humidity properties and cloud retrieval)

Integrated trace gas (at least ozone) measurements

Column aerosol measurements from sunphotometers
