Variable Relevance for measuring this variable Operational limitations Explanation
Cloud cover 5 - marginal Daylight only.. Dense cloud only. VIS channel(s)
Fire fractional cover 5 - marginal Cloud sensitive.. Coarse spatial resolution.. Daylight only. VIS channels
Snow cover 5 - marginal Cloud sensitive.. Daylight only. VIS channel(s). Frequent sampling (GEO) improves probability of cloud-free views
Wind (horizontal) 5 - marginal Cloud or water vapour tracers needed.. Daylight only. VIS channel(s). Frequent sampling (GEO) enables inference from cloud motion
