Gap analyses by variable or by type of mission or by WIGOS subcomponent
Variable sorting criteria
Each instrument is assigned with a 5-step rating, evaluated as a blend of several elements such as the uncertainty, the vertical resolution, and the frequency and spatial resolution of the retrieved measurement in comparison with the space-time variability of the geophysical parameter. For this particular Variable, the rating is driven by:
the capability to observe atmospheric water by passive (MW) or active (radar) techniques;
the exploited MW bands (windows or sounding).
RATING CRITERIA:
1
Precipitation radar in Ku- and Ka- band
MW radiometer with both 54 and 183 GHz, in GEO
2
Ku-band precipitation radar
High-resolution MW radiometer with both window channels including 90 GHz, and sounding channels, in LEO
3
MW radiometer with both window channels including 90 GHz, and 54 and/or 183 GHz channels, in LEO
TIR radiometer, in GEO
4
MW radiometer with only window channels, including 90 GHz, in LEO
High-resolution MW radiometer with only window channels, missing 90 GHz, in LEO
MW sounder in the bands 183 and (54 or 118) GHz, in LEO
5
MW radiometer with only window channels missing 90 GHz, in LEO
MW sounder with either 54 or 183 GHz, in LEO
W-band cloud radar
Radio occultation sounder splitting polarisation
