Beginning with the launch of the DMSP F-16 satellite on 18 October 2003, the SSMIS marks the commencement of a new series of passive microwave conically scanning imagers and sounders planned for launch over the next two decades. So roughly it will serve from 2003 to 2023.
Basic info about microwave bands:
Frequency : 0.3GHz 1GHz 3Ghz 30GHz 60GHz 90GHz 180GHz 300GHz
Wavelength : 30cm 10cm 1cm 0.5cm 0.33cm 0.16cm
|<---- SSMIS bands ---->|
Basic length unit info:
1meter (m) =
100 centimeter (cm)
1,000 millimeter ( mm )
1,000,000 micrometer (µm) / micron (µ)
1,000,000,000 nanometer (nm)
1. SSMIS' improvement over SSM/I and SSM/T:
Special Sensor Microwave Imager (SSM/I) :
the surface and atmospheric retrievals
Special Sensor Microwave Temperature Sounder (SSM/T-1) and
Special Sensor Microwave Humidity Sounder (SSM/T-2):
the atmospheric temperature and water vapor sounding capabilities
SSMIS is kind of a mixer: The SSMIS imaging and sounding sensors share the same viewing geometry, thereby allowing surface parameters to be retrieved simultaneously .
2. What SSMIS can do:
The SSMIS instrument is able to estimate atmospheric temperature, moisture, and surface parameters from data collected at frequencies ranging from 19 to 183 GHz over a swath width of 1707 km. SSMIS is currently carried aboard DMSP-F16, -F17, and -F18 satellites, and is slated for future missions aboard DMSP-F19 and -F20. This document discusses the mission objectives, principles of operation, sensor specifications, and calibration information of the SSMIS instrument.
