Dear Colleagues-

I am a bit behind on this but here we are.

I have made profiles from a subset of the 76y run of WACCM - 1975-2020.  This
time I made profiles for all the gases in the model run (I hope they will be of
some use...) since its just some time.  I have added Frank's code for computing
a (near) common grid for each site and Gauthier's covariance code for the
ensemble.  The output is in a folder by site name and 4 files for each gas:

The site directories can be found here
ftp://acd.ucar.edu/user/jamesw/WACCM_test/V4

<gas>.prfs - all the profiles on the site specific grid
<gas>.txt  - average, max, min, std. dev. interpolated to site specific grid and
to a modified REFMOD grid for input to fastcode - the mod is to add 2 levels to
reach 127km.  Up to 100km it is the same default REFMOD grid
<gas>.cov  - n x n covariance matrix on the site specific grid
<gas>.ps   - postscript plots of each interpolation plus the covariance matrix
station.layers - output from site specific grid calculation

This update uses a more current version of WACCM.  For our averages the profiles
should be very similar to the previous test.  This version though will be better
documented and compared withg other models.  This version is currently being
used in the ongoing SPARC CCMVal tests.  Averages are for 1975-2020.  Profiles
for HCN & C2H6 are from a different model run for only 3 years.  Still no HF.

We hope that ou can beging to implement using the profiles for the apriori for
the target retrieval gases.

Martine and I will contact you soon on the next steps toward continuing
harmonizing retrieval parameters.

Kind Regards,
-Jim
