Full name Cross-nadir IR spectrometry (for chemistry) from LEO
Definition This type of mission designates IR spectrometers designed for use in atmospheric chemistry, in LEO.
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 extension of the spectral range through NIR, SWIR, MWIR and TIR bands;
  • the spectral resolution.

 Sorting criteria and colour code:

  1. IR spectrometer with resolution ≤0.07 cm-1 in the range 3.5 to 15 μm.
  2. IR spectrometer with resolution ≤0.13 cm-1 in the range 3.5 to 15 μm.
  3. IR spectrometer with resolution <=0.1 cm-1 in NIR and SWIR, and <=0.3 cm-1 in the range 5 to 15 μm; OR <=2.8 cm-1 in the range 3.5-5 μ, <=1.4 cm-1 in the range 5-8.5 μm, and <=0.7 cm-1 in the range 8.5-15 μm.
  4. R spectrometer with resolution <=1.4 cm-1 in the range 5-8.5 μm, and <=0.7 cm-1 in the range 8.5-15 μm; OR very-high resolution in specific narrow bands of CH4, CO and (possibly) CO2.
