# The purpose of this readme file is to give a guide to creating your
  own radiative transfer coefficients for the universal code. It is
  not designed as a substitute for the kspectrum or LMDZ GCM manuals,
  which can be found elsewhere.


1. Creating the high resolution spectral data

   To do this we use 'kspectrum', which was written by Vincent Eymet
   and is freely available online at: ''. See the manual on the
   website for a guide to installation. Once the code is installed,

   decide p, T arrays

2. Converting to correlated-k coefficients

   There are two ways to do this: with Vincent Eymet's code
   'kdistribution', or with a simpler code written by Robin Wordsworth
   called 'generate_kmatrix'. The latter code is less sophisticated
   and probably a little less accurate, but it has an advantage in
   that it works.

3. Running the GCM with the new data
