Variable Relevance for measuring this variable Operational limitations Explanation
Fire fractional cover 3 - high Infrequent coverage. X-band SAR. High resolution, for fire boundary detection
Fraction of vegetated land 3 - high No specific limitation. X-band SAR
Glacier cover 2 - very high Long time for mapping. X-band SAR for accurate boundary detection
Glacier motion 5 - marginal Infrequent coverage. X-band SAR for interferometry between images taken at time intervals
Glacier topography 3 - high Long time for mapping. X-band SAR for interferometry between images taken at time intervals
Ice sheet topography 3 - high Long time for mapping. X-band SAR for interferometry between images taken at time intervals
Land cover 3 - high No specific limitation. X-band SAR
Land surface topography 3 - high Long time for mapping. X-band SAR for interferometry between images taken at time intervals
Oil spill cover 1 - primary Infrequent coverage. X-band SAR
Sea-ice cover 1 - primary No specific limitation. X-band SAR
Sea-ice elevation 4 - fair No specific limitation. X-band SAR. Sea ice elevation measured by interferometry
Sea-ice thickness 4 - fair Change detection only. X-band SAR. Sea ice elevation measured by interferometry. Thickness inferred by ice model
Sea-ice type 2 - very high No specific limitation. X-band SAR. Type interpreted as age/roughness
Snow cover 3 - high Thick snow only.. Infrequent coverage. X-band SAR
Snow status (wet/dry) 4 - fair Thick snow only.. Infrequent coverage. X-band SAR
Snow water equivalent 3 - high Change detection only.. Infrequent coverage. X-band SAR. SWE is retrieved by grigging with data from ground networks
Soil moisture at surface 3 - high Strongly affected by vegetation.. Infrequent coverage. X-band SAR
Soil type 3 - high No specific limitation. X-band SAR
Vegetation type 5 - marginal No specific limitation. X-band SAR
