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.

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 Satellite-

based 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)

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

Proposed Observing System Architecture

Benchmark Network~10 stations

Upper Air Reference Network30-40 stations

GCOS Upper Air Network (GUAN)

163 stations

Comprehensive observing networkAll stations, observing systems, reanalyses

etc.

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

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
