President’s Statement
Our cooperation will
enable us to develop the
capability to predict
droughts, prepare for
weather emergencies,
plan and protect crops,
manage coastal areas
and fisheries, and
monitor air quality
Group on Earth Observations
(GEO)
• Membership open to all countries
– 60 countries (including the EC) are now
represented
• International organizations are participants
– 43 organizations are now represented
• Organized into 5 subgroups
• Established GEO Secretariat
• Established Implementation Plan Task Team
GEO Moves Forward
Working Towards Implementation of the Global Observation System of Systems
(GEOSS)
Received approval for formal GEO organization and 10-year
implementation plan
Held GEO-I in May 2005, and GEO-II in December 2005
New GEO Secretariat Director, Jose Achache
Agreed to 2006 Work Plan and adopted a budget
Formally created GEO Committees
GEONETCast as tangible near term project to implement
GEOSS
US announced intention to move GOES satellite over South
America to help offset lack of sounder data in that region

Integrated Observations & Data Management
Intercalibration of foreign and domestic satellites is fundamental to GEOSS
Societal Benefit Areas
1. Improve Weather Forecasting
2. Reduce Loss of Life and Property from Disasters
3. Protect and Monitor Our Ocean Resources
4. Understand, Assess, Predict, Mitigate, and Adapt to
Climate Variability and Change
5. Support Sustainable Agriculture and Combat Land
Degradation
6. Understand the Effect of Environmental Factors on
Human Health and Well-Being
7. Develop the Capacity to Make Ecological Forecasts
8. Protect and Monitor Water Resources
9. Monitor and Manage Energy Resources
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
ECMWF
Satellite Observations Have Contributed to
Improved Monitoring of Global Climate
Change

Federal Study Finds Accord on Warming
By ANDREW C. REVKIN
A 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
Total Solar Irradiance
(Wilson, 03)
– 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
(After Frohlich)
• 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
Equator Crossing Time
Is the Earth Greening?
• Good calibration and
intercalibration are crucial
Pinatubo

(After Heidinger)
Next Steps: NOAA/NIST Initiative in
Satellite Calibration and Intercalibration
•
A Government program is needed to assure instruments meet specification and prelaunch 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
