BackForward Variable: Upward spectral radiance at TOA

Definition
Full name Upward spectral radiance at TOA
Definition Upward radiant power measured at the top of the atmosphere per area unit, per solid angle, and per wavelength interval. Spectral range 0.2-200 µm. Resolving power ?/??= 1000. Accuracy quoted as SNR (Signal-to-Noise-Ratio), actually SNR^-1 so that smaller figure means better performance, as usual.
Measuring Units W.m-2 .nm-1 . sr-1 Uncertainty Units SNR-1
Horizontal Res Units km Vertical Res Units
Stability Units SNR-1 (Stability /decade)
