Dr. Gregory Leptoukh of the Goddard Earth Sciences Data and Information Services Center (GES DISC) is in England this week, attending a workshop on data quality assurance for remote sensing data. The workshop is entitled "Providing Harmonised Quality Information in Earth Observation Data by 2015", and is hosted by Rutherford Appleton Laboratory - Space (RAL Space). The workshop is convened under the Quality Assurance Framework for Earth Observation (QA4EO) program of the Group on Earth Observations (GEO). The site of the workshop, Rutherford Appleton Laboratory, is a national science laboratory of the United Kingdom, located in Oxfordshire.
The program for the workshop can be viewed here. More information on the goals of QA4EO can be found here.
The GES DISC maintains a large archive of earth observation data from NASA missions, which are available through the Mirador data search and access tool. The GES DISC has worked on methods to monitor and maintain data quality in archived satellite data products for many years, and has developed innovative ways to deliver data quality information to researchers. An example of these efforts is the Data Quality Screening Service in Mirador. Dr. Christopher Lynnes of the GES DISC gave a presentation entitled "Ambiguity of Quality in Remote Sensing Data" at the 2010 Fall Meeting of the American Geophysical Union.
