Achieving Satellite Instrument Calibration for Climate Change

1. Achieving Satellite Instrument Calibration for Climate Change May 16-18, 2006

2. Outline • Background • Workshop • Workshop Schedule (Big Picture) • Breakout Groups • Post-Workshop Publication • Sponsors and supporters • Committee members

3. Background • ASIC3 is a follow-on workshop to “Satellite Instrument Calibration for Measuring Global Climate Change” (Nov. 2002) • Defined absolute accuracies and long-term stabilities of global climate data sets that are needed to detect expected trends • Assessed needed satellite instrument accuracies and stabilities • Evaluated ability of current observing systems to meet these requirements

4. Workshop • Community conceived workshop • Community recognition that calibration challenges exist for climate change measurements • Bring community experts together to recommend improvements • Primary workshop objective • Formulate a national roadmap for a calibration system that will allow us to achieve the requirements associated with the monitoring of long-term global climate change

5. Workshop Schedule • First half (~1.5 days) • Invited presentations - selected to provide information for consideration in breakout groups • Grouped into 4 sessions • Agency Roles • Review Requirements for Measuring Global Climate Change • Calibration Status for Current Instruments and Plans for Future Instruments • Concepts and Methodologies for Achieving Calibration of Global Climate Change Measurements • Second Half (~1.5 days) • Breakout Groups • IR • UV, VIS, NIR • Microwave • Active • Broadband • Intercalibration of Instruments • National Roadmap: Coordination Mechanisms, Agency Roles, Implementation solutions.

6. Breakout Groups • Breakout groups are an important component of the workshop • Groups 1 to 6 (Instrument related) • Address (1) current status, (2) impediments to progress, (3) recommendations to accelerate progress • Group 7 (National Roadmap) • Obtain input from groups 1 to 6 • Address (1) coordination mechanisms, (2) agency roles, (3) Implementation solutions • George Ohring is overall breakout group leader

7. Post-Workshop Publication • Community document that may be used as a reference by policy makers, leaders, scientists and engineers • Outline • Executive Summary • Background • Calibration of Infrared Instruments • Calibration of UV, VIS, and NIR Instruments • Calibration of Microwave Instruments • Calibration of Broadband Instruments • Calibration of Active Instruments • Intercalibration of Instruments • National Roadmap • Edited by George Ohring and published by NOAA

8. Sponsors and Supporters • Thank you for your contributions and continued support! • NIST • NOAA • NPOESS/IPO • NASA • WMO
