• 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,

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

6
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)

7
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 Satellite-based
  Climate Products
• An interruption in a national satellite
  contribution should not mean a failure
  in the Climate Record

8
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)

GCOS Reference Upper Air NetworkRationale

• 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
  spatially-comprehensive global observing systems
  (including satellites)
• Measure large suite of co-related climate
  variables

GRUAN Progress to Date

• Climate Requirements Established Boulder
  Workshop 2005
• Instrumentation/Siting Options Assessed Seattle
  Workshop 2006
• Report on Requirements, Siting, Instrumentation
  July 2007
• Lindenberg designated as Lead Centre Director
  Holger Voemel
• Initiation Meeting at Lindenberg 25-28 February
  Start small, but start
• Community Presentations
• WMO CIMO, CBS groups
• WCRP Observations and Analysis Panel
• GCOS Atmospheric Observation Panel for Climate
• AMS
• Ozone Research Managers
• Lindenberg Report to be released Invitations to
  stations

13
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
