Workspace Method propmat_clearsky_fieldCalc

Description

Calculate (vector) gas absorption coefficients for all points in the
atmosphere.

This is useful in two different contexts:

1. For testing and plotting gas absorption. (For RT calculations, gas
absorption is calculated or extracted locally, therefore there is no
need to calculate a global field. But this method is handy for easy
plotting of absorption vs. pressure, for example.)

2. Inside the scattering region, monochromatic absorption is
pre-calculated for the entire atmospheric field.

The calculation itself is performed by the
propmat_clearsky_agenda.
