  1. The radiometric calibration problem • Official, current key data • Key data obtained from NASA sphere measurements • Key data obtained from spectralon measurements August 30, 2004

  2. Official key data: orbit 5973 Problem in spectral channel 1  Why? What happened?

  3. NASA sphere key data: orbit 5973 Deviation is somewhat larger… no improvement…

  4. Spectralon key data: orbit 5973 Deviation comparable to official key data… so no improvement…
