Details on this mission type
Full name Instruments covering 400-700 nm
Definition VIS range, for clouds, surface, aerosol, ocean colour, and the ozone Chappuis band. Involved instrument types: • Moderate-resolution optical imager, • High-resolution optical imager, • Cross-nadir scanning SW sounder, • Limb sounder.
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:

  • the multi-purpose capability (e.g., inclusion of MWIR and TIR channels)
  • the number of VIS channels and their bandwidth
  • the orbit (GEO or LEO).

The rating criteria are as follows:

  1. Multi-purpose radiometers for clouds, aerosol and ocean colour, flown in LEO; OR Multipurpose radiometer for cloud analysis flown in GEO or Molniya.
  2. Multi-spectral, multi-angle, polarimetric radiometer for clouds, aerosol and BRDF; OR VIS spectrometer for aerosol, clouds and the ozone Chappuis band.
  3. Multi-purpose imager essentially for cloud analysis, flown in LEO; OR Multipurpose imager essentially for cloud analysis flown in GEO or Molniya; OR Ocean colour radiometer flown in GEO.
  4. Hyperspectral high-resolution imager for vegetation fine analysis; OR High-resolution imager with stereo capability for strategic sampling or cartography; OR High-resolution imager for land observation.
  5. Limb sounder for atmospheric chemistry and aerosol in the high-troposphere/low-stratosphere.
