API Reference
=============
.. currentmodule:: pyrt

This page describes the pyRT_DISORT API, where the API is grouped by
functionality. Many docstrings contain practical example code.

Columns
-------
Perhaps the most important set of DISORT inputs is the optical depth, single
scattering albedo, and phase function in each layer of the model. You can
create these on a per-aerosol basis and store them in a Column object. These
can easily help you create the optical properties of the composite atmospheric
model.
