GCOS Reference Upper Air Network: Progress to Date
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
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)
Reconsidering the Observing System: Toward a GCOS “Comprehensive Report”
Lessons fromIPCC (2007)
GCOS Performance Monitoring Data
GCOS “Comprehensive Report” (2009)

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.
Spatial density
Climate driven
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

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
Proposed Initial GRUAN Sites
