Variable Relevance for measuring this variable Operational limitations Explanation
Cloud top height 4 - fair Infrequent coverage.. Daylight only. NIR hyperspectral channels to estimate the total-column O2 above the cloud top as measured around 760 nm
Leaf Area Index (LAI) 2 - very high Cloud sensitive.. Daylight only.. Infrequent coverage. NIR and SWIR hyperspectral channels
Specific humidity 4 - fair Cloud sensitive.. Very coarse vertical resolution.. Infrequent coverage.. Daylight only. NIR hyperspectral channels including the ro-sigma-tau band of water vapour around 940 nm
Integrated Water Vapour (IWV) 5 - marginal Cloud sensitive.. Infrequent coverage.. Daylight only. NIR hyperspectral channels covering the 940 nm band
