Workspace Variable sensor_los
The sensor line-of-sight (LOS) for each measurement block. Line-of-sights are specified by giving the zenith and azimuth angles. Column 1 holds the zenith angle. This angle is simply the angle between the zenith and LOS directions. For 1D and 3D the valid range is [0 180], while for 2D angles down to -180 degrees are allowed. Negative angles signifies for 2D observations towards lower latitudes, while positive angles means observations towards higher latitudes. Nadir corresponds throughout to 180 degrees. The azimuth angle is given with respect to the meridian plane. That is, the plane going through the north and south poles. The valid range is [-180,180] where angles are counted clockwise; 0 means that the viewing or propagation direction is north-wise and +90 means that the direction of concern goes eastward. See further the ARTS user guide (AUG). Use the index to find where this variable is discussed. The variable is listed as a subentry to "workspace variables". Usage: Set by the user. Unit: [ degrees, degrees ] Size: [ number of measurement blocks, 1 or 2 ]
