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

1. Agency Roles2. Review Requirements for Measuring Global Climate Change3. Calibration Status for Current Instruments and Plans for Future Instruments4. Concepts and Methodologies for Achieving Calibration of Global Climate Change

Measurements

• Second Half (~1.5 days)– Breakout Groups

1. IR2. UV, VIS, NIR3. Microwave4. Active5. Broadband6. Intercalibration of Instruments7. 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
