Importance of Cal/Val and Next Steps

Satellite Observations Have Contributed to More Accurate
Weather Forecasts
• Southern Hemisphere forecasts are now as accurate as NH forecasts
• Today’s 5-day forecasts as accurate as 3-day forecasts 25 years ago
• BUT …..forecast centers remove satellite biases approximately and empirically
• Improved calibration and intercalibration can be expected to lead to further gains in forecast accuracy

Satellite Observations Have Contributed to Improved Monitoring of Global Climate
Change
One Example:
May 3, 2006Federal Study Finds Accord on Warming By ANDREW C. REVKINA scientific study commissioned by the Bush
administration concluded yesterday that the lower atmosphere was indeed growing warmer ……
Above conclusion based on careful analyses of NOAA’s MSU observations (one analysis is shown on right)
But enormous challenges remain in monitoring global climate change

Challenges in Monitoring Global Climate Change from Space
• Need to construct time series by stitching together observations of many satellites
• Extremely small signals– Atmospheric temperature
trends as small as 0.1 C/decade
– Ozone changes as little as 1%/decade
– Variations in the sun’s output as tiny as -0.02%/decade
• Different analyses of observations vary from:
-0.023 to +0.25 W/m2
• Good calibration and intercalibration are crucial

Is the Earth Greening?
• NOAA’s AVHRRs have been used to construct a time series of Vegetation Index that indicates a greening Earth – but we don’t know if this is really happening because of uncertainties in calibration and intercalibration of the different satellites
• Good calibration and intercalibration are crucial

Next Steps: NOAA/NIST Initiative in Satellite Calibration and Intercalibration
• A Government program is needed to assure instruments meet specification and pre-launch tests are traceable to SI standards, and the on-orbit satellite instrument observations are well calibrated and validated by means of careful analysis of instrument performance, satellite intercalibration and validation with reference sites
• On-orbit validation is needed for foreign satellite instruments to meet GEOSS objectives
• Inadequate calibration can result in economic benefit losses in the billion dollar range.
– Degraded climate trends and projections– Degraded weather forecasts– Degraded ocean and coastal ecosystems assessments– Degraded hazard support information (fires, flash floods, droughts)
• Benefits of improved calibration/intercalibration– Independent confirmation to ensure instruments meet specifications.– Independent recommendations for corrective actions– Better calibrated satellite observations for ecosystems, climate and weather applications
• Resulting in improved information for society
• Fundamental prerequisite for an Integrated Global Earth Observing Systems of Systems (GEOSS)
– Need to properly characterize and minimize observational errors before information can be used in Earth System Models.

Next Steps: Global Space-based Inter-Calibration System (GSICS)
• GSICS: A new World Meteorological Organization (WMO) program
• Overarching Goal: Ensure the comparability of satellite measurements provided at different times, by different instruments under the responsibility of different satellite operators
• Participants: WMO, satellite agencies, national standards institutes, national data centers, major NWP centers, and national research laboratories
• NOAA is taking a leading role

Next Steps: ASIC3 National Roadmap
• By developing a National Roadmap for improving satellite instrument calibration and intercalibration, this workshop will advance the nation’s ability to monitor, understand and predict our natural environment
• Best wishes for a successful Workshop
