iyInterpCloudboxField

Interpolates the intensity field of the cloud box.

Determines the intensity field at the position and direction specified by rte_pos and rte_los. The position can be both inside the cloud box or at its edge.

The interpolation in the spatial dimensions is linear.

For the zenith angle dimensions several options for controlling the interpolation are at hand. Default is linear interpolation. Higher order polynomial interpolation is activated by setting za_interp_order to a value > 1. Default is to perform the interpolation separately for [0,90[ and ]90,180]. To handle 90 degree or use the full range ([0,180]) as basis for the interpolation, set za_restrict to 0. You can select to use cos(za) as the independent variable (instead of za) by setting cos_za_interp to 1.

For the azimuth dimension the interpolation order can be selected, in the same manner as for zenith.
