issue with AOD output using chem opt 202 and mozbc
Paul Goddard
Hello,
Thank you for helping me get WRF Chem running a couple months ago. I have made some good progress -- I am (mostly) successful in running with chem_opt 202.
However, I am getting very low values by calculating AOD from the TAUAER (and EXTCOF) -- two or three orders of magnitude too small. Also, the output variables AOD2D and 3D are empty. I've been troubleshooting this issue with my colleagues for a few weeks, and thought it would be a good idea to see whether you have come across this issue before.
Some details:
I am using the current version of WPS and WRF, 4.2(.1)
I am using chem opt 202 and mozbc with CAM-CHEM data for initial and BCs
of chemistry. I attached the namelist.input
I also attached a PDF that runs through the AOD550 field from about 1 week
into the simulation to 4 weeks into the simulation. You can see that
within the domain, the AOD550 pattern looks very much like sea salt
flux, and changes with sea salt flux for each time step. However, other
variables (meteorological and CCN at 1% saturation) appear to me to be
reasonable.
I did find a similar issue on the WRF Support Forum, though the issue
was not completely resolved. However, they mention that the computing
environment may be the culprit. Currently I am on a Cray Machine, but
I have a GNU environment set up to work in -- I checked with
the IT people here at my University, and they don't think that's the issue; but I
may just start all over with WRF in another environment to see if I
can get passed the AOD issue.

Whenever you have time, if you could share your thoughts on the issue, I would greatly appreciate it.
Best,
