events are visible in the SST
and wind retrievals
DMSP satellites F16 and forward carry the Special Sensor Microwave
Imager/Sounder (SSMIS). F16 was launched in October 2003 into a sunsynchronous orbit at an altitude of 830 km and a LECT of 8 AM/PM. SSMIS has 24
channels, several of which are similar to the SSM/I set (19.35, 22.2, and 37.0 GHz).
The additional channels are intended for atmospheric sounding. The calibration is
completed similar to SSM/I using a cold reflector and hot absorber. SSMIS has two
main problems, an emissive antenna and non-uniform hot absorber. Corrections for
these issues have been developed and implemented.
Future PMW radiometers include JAXA’s Global Change Observation Mission –
Water (GCOM-W) AMSR2, the National Polar Orbiting Earth observing System of
Systems (NPOESS) C2 satellite will carry the Microwave Imager Sounder (MIS),
