  1. CGMS, GSICS & SCOPE-CM18th Session GCOS Steering Committee Barbara J. Ryan Director, WMO Space Programme 29 September 2010 Geneva

  2. Coordination Group for Meteorological Satellites (CGMS) • CGMS is a forum for the exchange of technical information on geostationary and polar orbiting meteorological satellite systems • http://www.wmo.int/pages/prog/sat/CGMS/CGMS_home.html • Contains information on the following topics: • CGMS scope • CharterCGMS membership • CGMS organization and Secretariat (EUMETSAT) • CGMS origin • CGMS documents • Latest satellite status • CGMS-related scientific user groups (ITWG, IWWG, IPWG, IROWG)   • CGMS Members section • CGMS Virtual Laboratory for training in satellite meteorology • Global Space-based Intercalibration System (GSICS) • Sustained, Coordinated Processing of Environmental Satellite Data for Climate Monitoring (SCOPE-CM) • Miscellaneous links to sites of interest to CGMS

  3. From Observations to Users ConsistentCalibrateddata sets Sustained QC products Satellite data Satellites & sensors Wider access Users(Programmes/ Members GSICS GOS/WIGOS SCOPE-CM IGDDS • Vision founded on User Requirements and Gap Analysis • Space-based Architecture for Weather and Climate monitoring • Global Space-based Inter-calibration System (GSICS) • Sustained Co-Ordinated Processing of Environmental satellite data (SCOPE) for climate monitoring and operational applications • Data/Product Dissemination Strategy (IGDDS/WIS) • Coordination and technical support mechanisms include:CM, CGMS, CEOS, CBS/ET-SAT & ET-SUP

  4. Space-based Component of WMO’s Global Observing System (GOS) Intercalibration of instruments for comparability of measurements from different instruments

  5. Motivation Applications require well-calibrated and inter-calibrated measurements Radiance Assimilation in Numerical Weather Prediction Data Fusion Climate Data Records Expanding Global Observing System (GOS) Inter-calibration of instruments achieves comparability of measurements from different instruments

  6. Global Space-based Inter-Calibration System (GSICS) To enhance and sustain calibration and validation of satellite observations To intercalibrate critical components of the Global Observing System (GOS) – to climate quality benchmark observations and/or reference sites To provide corrected observations and/or correction algorithms to the user community for current and historical data GSICS Implementation Plan and Programme formally endorsed at CGMS-34 (Nov. 2006)

  7. Actions Quantify the differences – magnitude and uncertainty Correct the differences – physical basis and empirical removal Diagnose the differences – root cause analysis

  8. Organizations contributing to GSICS NOAA NASA NIST EUMETSAT CNES CMA JMA KMA WMO Observers: JAXA ESA CEOS Precipitation Constellation is working with GSICS via GPM X-Cal Working Group Current focus is on the intercalibration of operational satellites, and makes use of key research instruments like AIRS and MODIS as reference instruments

  9. Global Space-based Inter-calibration System (GSICS) POLAR- POLAR intercalibration • To ensure consistency of datasets from different missions and operators • Implementation Plan adopted Nov.2006 • 8 Organizations currently contributing (+WMO) GEO versus Polar-orbiting Simultaneous Nadir Overpass (SNO) inter-calibration method • Images: NOAA/NESDIS

  10. Calibration is Critical for Climate Change Detection Before Intercalibraion After Intercalibration Calibration uncertainties translate to uncertainties in climate change detection. Trend of global oceanic total precipitable water decreases from 0.54 mm/decade to 0.34 mm/decade after intercalibration.

  11. IASI AIRS Ch2 Ch4 Ch3 Ch6 First international coordinated GSICS project is the intercalibration of geostationary infrared channels with IASI and AIRS Web Accessible

  12. GSICS Correction Algorithm for Geostationary Infrared Imagers GSICS will provide correction coefficients for all GEOs from 2003 (beginning of AIRS record) to present The first major deliverable to the user community is the GSICS correction algorithm for geostationary satellites. The user applies the correction to the original data using GSICS provided software and coefficients. The correction adjusts the GOES data to be consistent with IASI and AIRS. The figures to the left show the difference between observed and calculated brightness temperatures (from NCEP analysis) before and after correction The bias is reduced from 3 K to nearly zero Before: 3K Bias After: ~ 0K Bias
