Details on this mission type
Full name IR temperature/humidity sounding from LEO
Definition This type of mission designates medium spectral resolution spectrometers or radiometers operating in the IR part of the spectrum, 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 resolution (hyperspectral or radiometric);
  • scanning capability.

 Sorting criteria and colour code:

  1. IR spectrometer with resolution <=0.7 cm-1 in the range 8.5-15 μm, <=1.3 cm-1 in the range 5-8.5 μm and <=2.5 cm-1 in the range 3.5-5 μm. High vertical resolution temperature/humidity profiling in the whole troposphere and low stratosphere
  2. IR spectrometer with resolution <=0.7 cm-1 in the range 8.5-15 μm, <=1.3 cm-1 in the range 5-8.5 μm, and <=0.7 cm-1 in the range 15-22 μm. High vertical resolution temperature/humidity profiling in mid- high troposphere and low stratosphere
  3. IR spectrometer with resolution <=0.7 cm-1 in the range 8.5-15 μm and <=1.3 cm-1 in the range 5-8.5 μm. High vertical resolution profile through the mid-high troposphere
  4. IR radiometer with >=6 channels in the CO2 15 μm band, >=2 channels in the H2O 6.3 μm band, and >=3 channels in the CO2 4.3 μm band. Coarse vertical resolution temperature/humidity profiling. 
  5. IR radiometer with >=6 channels in the CO2 15 μm band and >=2 channels in the H2O band 6.3 or 18  μm. Coarse vertical resolution temperature profiling [generally heritage instruments]
