1. U.S. Department of the Interior U.S. Geological Survey International Satellites – Supporting Global Earth Observation ASPRS Meeting - 17 November 2011 Greg Stensaas Chair, CEOS Working Group on Calibration and Validation Remote Sensing Technologies Project Manager USGS Earth Resources Observation and Science (EROS) Center, Sioux Falls, SD

2. Many datasets, Many opportunities > 100 EO satellites in orbit Operated by > 34 countries, many with surface resolutions <1 m Many expected to be launched in current decade Common processes and procedures are lacking for defining quality

3. 3 The Group on Earth Observations (GEO) (founded 2002) is a voluntary partnership of 89 governments and 61 international organizations. GEO’s GEOSS must deliver comprehensive “knowledge / information products” worldwide and in a timely manner to meet the needs of its nine “societal benefit areas”. This will be achieved through the synergistic use and combination of data derived from a variety of sources (satellite, airborne and in- situ) through the coordinated resources and efforts of the GEO members. Achieving this vision (2015) requires the establishment of an operational framework to facilitate interoperability and harmonization. “Community” requirement ClimateWeather Strong Requirement Drivers

8. Current and Future EO Satellites 8 112 different CEOS Earth observation satellite missions are estimated to be currently operating (November 2011). Many of these comprise series of missions planned to provide the continuity which is essential for many observations and applications. Current plans supplied by CEOS agencies estimate that in the order of 100 new satellite missions will be launched for operation between 2011 and 2016. The next few years will mark a significant era for satellite Earth observations, with half of these new missions to be launched by the end of 2013.

15. We need to understand the error · All systems and models have some degree of error · Calibration compensates for errors and improved measurement accuracy is possible · Bias between sensors need to be defined and there is a strong need for better error characterization · Data record error is essential for use in climate and change assessment · Different groups can produce defensible, but statistically inconsistent estimates of trends · Need a consistent playing field 15
