The processor is still under development, and the calibration is not final. The current status of the processor is that only some of the calibration parameters have been adequately determined. In particular, there is an arbitrary phase offset for each interferogram, and therefore an arbitrary velocity offset in the velocity map. There is evidence of inadequate motion measurement and compensation, as well as interferometric phase center alignment: phase variations along-track and a residual phase-ramp across the scene are seen in some of the ATI data sets. Note that phase variations over land are expected due to topography: along-track interferometric processing makes use of an elevation reference for motion compensation. Where this reference is not constant, there will be motion compensation phase variations introduced. The elevation reference is constant over the ocean surface, so this artifact is unique to the land. There is no radiometric calibration for these data.
