Details on this mission type
Full name MW temperature/humidity sounding from LEO
Definition This type of mission designates MW radiometers operating in O2 or H2O absorption bands fo IR sounding in nearly all-weather conditions, in Low Earth Orbit.
Relevant instruments and their contribution

The sorting column describes how the instruments, by design, have the potential to contribute to certain pre-determined capabilities, assuming nominal operation of space and ground segments. For this particular capability, instrument performance is considered to be driven by:

  • spectral range, covering both oxygen (for temperature) and water vapour bands, or only one of them
  • scanning mechanism: cross-track or conical. 

Sorting criteria and colour code:

  1. [Green] Cross-track MW sounder, >=9 channels in the 54 GHz band and >=3 channels in the 183 GHz band. Observation of temperature and humidity.
  2. [Light green] Conical-scanning MW imager/sounder, >=9 channels in the 54 GHz band and >=3 channels in the 183 GHz band. Observation of temperature and humidity.
  3. [Yellow] Conical-scanning MW imager/sounder, >=7 channels in the 54 GHz band, >=4 channels in the 118 GHz band and >=3 channels in the 183 GHz band; OR cross-track MW sounder, >=7 channels in the 118 GHz band and >=3 channels in the 183 GHz band. Observation of temperature and humidity.
  4. [Orange] Cross-track MW sounder, >=9 channels in the 54 GHz band. Observing only temperature.
  5. [Red] Cross-track MW sounder, >=3 channels in the 183 GHz band. Observing only humidity.
