Details on this mission type
Full name Imagery with special viewing geometry
Definition This type of mission designates VIS/IR imagers viewing under different angles for specific purposes : accurate atmospheric correction, anisotropy effects, optimal geometry to exploit multi-polarisation, need for reconstructing irradiances from observed radiances, etc.
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 number of different viewing angles to capture anisotropy characteristics;
  • the extension of the spectral range through theVIS, NIR and SWIR, MWIR and TIR bands;
  • the channel bandwidth in the VIS/NIR bands.

 Sorting criteria and colour code:

  1. VIS/NIR/SWIR polarimetric radiometer with >=10 viewing angles, >=4 channels in VIS and >=2 channels in NIR and SWIR.
  2. VIS/NIR polarimetric radiometer with >=10 viewing angles, >=4 channels in VIS and >=2 channels in NIR.
  3. VIS/NIR radiometer with >=8 viewing angles, >=3 channels in VIS and >=1 channel(s) in NIR.
  4. VIS/IR radiometer with >=2 viewing angles, >=2 channels in VISand the TIR window ~11 μm, and >=1 channel(s) in NIR, SWIR and the MWIR window ~3.7 μm.
  5. VIS/IR radiometer with >=2 viewing angles, >=1 channel(s) in VIS and the MWIR window ~3.7 μm, and >=2 channels in the TIR window ~11 μm.
