Computes ppath_field from “standalone” sensors looking upwards from 0 m altitude with zenith angles range [0, 90], downwards from the top of the atmosphere covering the zenith angle range from 180 degrees to the surface tangent minus 1e-4 degrees, and through the limb covering at the same position as the downwards looking sensor covering the zenith angle range from the surface tangent plus 1e-4 degrees to 90 degrees minus 1e-4 degrees.
The top of the atmosphere is from
z_field
(-1, 0, 0) [python range notation].The field will consist of 3 * nz arrays structured as [up, limb, down]
The intent of this function is to generate a field so that calculations of
ppvar_iy
of all the fields will cover the zenith angle space of all positions inz_field
