Vicarious Calibration – Let the Data Do All the Work!

, 2015
Radiometric Calibration of optical satellite systems has been a key aspect of satellite remote sensing since the launch of the first Landsat sensor in 1972. Initially the approach to achieve this goal was based in on-board systems using lamps.

Sources and assumptions for the vicarious calibration of ocean color satellite observations

, 2008
Spaceborne ocean color sensors require vicarious calibration to sea-truth data to achieve accurate waterleaving radiance retrievals. The assumed requirements of an in situ data set necessary to achieve accurate vicarious calibration were set forth in a ...
