FY2010 - FY2011 Re-processing Information
A re-calibration of the 30" integrating sphere used to radiometrically calibrate the MASTER V/SWIR bands
was showing a loss of intensity in the shorter wavelengths. This sphere, which was calibrated regularly by
the Goddard EOS calibration team, had been historically quite stable. It became apparent that the BaSO4
coating was deteriorating, causing it to "yellow" (it has been replaced). Please do not hesitate to
contact us for further explanation or discussion.
