Variable Relevance for measuring this variable Operational limitations Explanation
Upward short-wave irradiance at TOA 2 - very high Information on BRDF needed. SW and Total (SW+LW) broadband channels. Frequent sampling (GEO) enable capturing diurnal variations, particularly due to clouds. Also, changing solar incidence angle helps with irradiance computation
Upward long-wave irradiance at TOA 2 - very high No specific limitation. LW radiance achieved by difference between Total and SW. Frequent sampling (GEO) enable capturing diurnal variations due to clouds.and water vapour rapid evolution
