Hoang:

I have run the model for a single time step and saved
vertical profiles of NO+, N+, and N2+. The model can
only be started from a primary history (not secondary
histories), and primary histories were saved only every
12 hrs in the cirris run. So the profiles are from
model day 28 (4/27), ut 0. Also, the vertical scale
for now is in the full pressure coords of the model,
i.e., -16 to +5 ln(p0/p). We can rerun it again with
interpolated to a height scale if you want.

There are 2 files on anon ftp on hao.hao.ucar.edu
in the dir /pub/foster. They are: nions_cirris.dat
and nions_cirris.ps. The .dat file is ascii data and
the .ps file is postscript line plots. You may want
to read the .dat file and plot log10 of these ions. 
(let me know if you need a fortran procedure to read
the ascii data).

Please let me know if these make sense, and what would
be the next step. I would think we would want these at
some specific height scale. (can you confirm that the
169 deg lon you gave is 169 east?)
