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 spectral band (short-wave or infrared or millimeter-submillimeter wave);
• the spectral scanning mode (spectrometric or filter radiometric);
• the vertical scanning mode (active scanning or by occultation).

 Sorting criteria and colour code:

1. UV/VIS/NIR/SWIR spectrometer with resolution <=1 nm in UV and SWIR, and <=1.5 in VIS and NIR.
2. UV/VIS and possibly NIR spectrometer with resolution <=1 nm in UV, and <=1.5 nm in VIS and NIR.
3. IR spectrometer with resolution <=0.05 cm-1 in MWIR and TIR, OR Mm-submm spectrometer in the range 60-250 GHz or possibly 60-650 or possibly 60-3000 GHz.
4. Very-high resolution spectrometer operating on lines in VIS and NIR with resolution <=0.03 nm; OR on lines in the range 307.9-309.4 nm (for OH).
5. Occultation spectrometers.
