Gap analyses by variable or by type of mission
Variable sorting criteria
|
|
Each instrument is assigned with a 5-step rating, evaluated as a blend of several elements. For this particular Variable, the rating is driven by:
- the exploited measurement technique (radar, MW radiometry, optical radiometry, lidar)
- the exploited frequency bands in MW (windows, sounding) or optical (VIS, NIR, SWIR, MWIR).
RATING CRITERIA:
|
|
1
|
- Cloud or precipitation radar
|
|
2
|
- MW radiometer with channels around 90 and possibly 37 GHz, and in sounding bands (54 and/or 118 and/or 183 GHz)
- MW radiometer with sounding channels (54 and 183 GHz) in GEO
|
|
3
|
- Radiometer with channels in VIS + NIR + SWIR + MWIR
- Radiometer with chnnels in VIS + MWIR + (NIR or SWIR)
- Radiometer or spectrometer with channels in MWIR + [VIS or (NIR + SWIR)]
|
|
4
|
- Radiometer or spectrometer with channels in VIS + NIR + SWIR
- Radiometer or spectrometer with channels in NIR + (VIS or SWIR)
|
|
5
|
- Backscatter lidar
- Lidar altimeters
