Variable Relevance for measuring this variable Operational limitations Explanation
Upward short-wave irradiance at TOA 1 - primary No specific limitation. LW and Total (SW+LW) broadband channels. SW computed as difference Total - LW. Cross-track and bi-axial scanning for BRDF. Supporting narrow-bandwidth channel(s)
Upward long-wave irradiance at TOA 1 - primary No specific limitation. LW and Total (SW+LW) broadband channels with supporting narrow-bandwidth channel(s)
