The ATMS TDR software
shall correct forpolarization-dependent emissivity and the polarization
twist of the instrument according to limits specified in the JPSS
Algorithm Specification Vol IV: SRSPF for ATMS RDR/TDR/SDR (474-00448-04-02) <Performance><polarization>. Current SRSPF value: Correct for polarization dependent emissivity of the rotating reflector and the absolute polarization twist of the instrument. A test to measure the emissivity might consist of measuring the same external target at different viewing angles and see if the brightness temperature is consistent. It will help understand the issue during ground testing and derive a correction term |
