Evaluation of Measurements

Variable	Relevance for measuring this variable	Operational limitations	Explanation
Cloud top temperature	2 - very high	Infrequent coverage.	TIR channels in the window around 11 micrometers and the water vapour band around 6.3 micrometers (for emissivity) to estimate cloud top height from its temperature
Fire fractional cover	2 - very high	Cloud sensitive.. Infrequent coverage.	TIR window channel(s) around 11 micrometers
Cloud top height	3 - high	Infrequent coverage.	TIR channels in the 11 micrometers window and the water vapour band around 6.3 micrometers (for emissivity) to estimate cloud top height from its temperature
Land surface temperature	4 - fair	Cloud sensitive.. Infrequent coverage.	TIR split window channels around 11 micrometers for water vapour correction
