Installing skdoas
=================

The skdoas package contains tools useful for performing Differential
Optical Absorption Spectroscopy (DOAS) style atmospheric retrievals. The tools
utilize SASKTRAN, a radiative transfer framework developed by the Atmospheric
Research Group at the University of Saskatchewan. See
https://arg.usask.ca/docs/sasktran/ for more information on SASKTRAN.

To install skdoas, first install SASKTRAN if it is not already installed::

   pip install sasktran -f https://arg.usask.ca/wheels/

Then install skdoas::

   pip install skdoas -f https://arg.usask.ca/wheels/

The Monte Carlo tools contained in this package require a branch of the
underlying SASKTRAN framework that is not available yet. Keep an eye out for
it in future versions.
