Response versus scan angle derived from polarization testing for JPSS-2 VIIRS

摘要

For the VIIRS (Visible Infrared Imaging Radiometer Suite) onboard the JPSS (Joint Polar Satellite System) missions, extensive ground testing is performed to characterize some aspects of the sensor that cannot be measured once the instruments are on-orbit. Two such parameters are the response versus scan angle (RVS) and polarization sensitivity. The pre-launch tests that characterize these parameters share a number of similarities. This paper will show that the polarization test data can be used to generate RVS results that are comparable to the results produced from the RVS test itself. The polarization test data also provides additional information about how the RVS changes with both scan angle and polarization state.
