Azimuth output angles (in degrees) in increasing order.
phi values
The radiance is output at phi and umu.
-
Sensor in the North (looking South): 0 deg
-
Sensor in the East (looking West): 90 deg
-
Sensor in the South (looking North): 180 deg
-
Sensor in the West (looking East): 270 deg
For all one-dimensional solvers the absolute azimuth does not matter, but only the relative azimuth phi-phi0.
