[gradsusr] any grads users know why ARWpost interp_method=1 does not work for WRF v3.3.1

[SMITH, JONATHAN WYNN. (GSFC-6140)]

Hello:

I have submitted this issue to wrfhelp at ucar.edu<mailto:wrfhelp at ucar.edu>.   But I thought I would try here to see if any grads users have run into the problem below using ARWpost.

For both ARWpost v2.2 and 3.1,  the interp_method = 1 is not produce .ctl and .dat files on the specified pressure levels for WRF/Chem v3.3.1 output.  However interp_method = 1 prints the .ctl and .dat  on the specified pressure levels with WRF/Chem v3.2.1 data. I have no choice but to use WRF/Chem v 3.3.1 for my research because the pre-processing emissions software for WRF/Chem includes a mercator projection that only works with v3.3.1 and not wit v3.2.


For example even with interp_method = 1 with WRF/Chem v3.3.1 output:

I get this message first

START PROCESSING DATA

   WARNING --- I do not recognize this data.
               OUTPUT FROM *             PROGRAM:WRF/CHEM V3.3.1 MODEL
               Will make an attempt to read it.

Then it just prints out the model levels

   16.19018
   16.38956
   16.58874
   16.78770
zdef   24 linear 1 1

hno3          24  0  HNO3 concentration (ppmv)

However with the v3.2 or v3.2.1, I do not get the messages and the data is printed on the specified pressure levels:

 225.00000
 200.00000
 175.00000
