VRT Flag: Flux-type Calculations Without Solid-angle |
or one could get the same answer using*FLG ZEN RAD OBS ! observer looking upwards at downwelling radiance ... *TAN 1.0 ! defines vertical path ... *OBS 25.0 ! observer at 25km ... *END
The advantage of the second approach is that multiple output levels can be selected by adding more numbers in the *TAN section*FLG ZEN RAD FLX VRT ! flux-type calc of downwelling radiance without solid-angle ... *TAN (or *LEV) 25.0 ! output at 25km ... *END
