chk_moz_vars: could not find O3_VMR_inst

[Shreta Ghimire]

Hello all, 

I am very new to WRF-CHEM and just started using Mozbc couple of days back. Any help and suggestions will be highly appreciated. 

I ran real.exe with chem_opt 202 and phot_opt = 4. Now i want to update IC and BC for WRF runs using mozbc with CAM-CHEM data. But i am getting the error "chk_moz_vars: could not find O3_VMR_inst in hb000.nc". I have both hb000.nc anc hb001.nc in the same folder. The file hb000.nc has the data for a day prior to my wrfinput_d01 and wrfbdy_d01, whereas hb001.nc has data for the same time period as wrf input and boundary files. 

I saw few posts on the group with the same error, but could not find any solution on how to fix it. 

Thank you in advance. 

This is my namelist:

do_bc     = .true.

do_ic     = .true.

domain    = 1

dir_wrf   = '../WRFV3/test/em_real/'

dir_moz = '/glade/scratch/ghimire/O3project/WRFV3-chem/MOZBC/'

you are using the namelist for the initial and boundary conditions from the global MOZART model. For guidance on using output from CAM-Chem or WACCM you have to look at the document that is provided on our WRF-Chem Tools website: https://www2.acom.ucar.edu/wrf-chem/wrf-chem-tools-community

Hello everyone.

Hope you are ok.

I have the same error, but I can't find a solution. wrf-chem-tools-comunuty web page leads me to WRF-Chem discussion forum that leads me here. I can't find the input namelist to use with CAM-Chem files.

I appreciate you can help me.

Kind regards, Stephanie.

Hi Stephanie,

Sorry for the late response. I am not sure if you are able to fix this issue yet but i will let you know what worked for me. 

If you look at the code mo_mozart_lib.f90 under section "public variables" line 34, character(len=9) :: moz_var_suffix = '_VMR_inst' it says _VMR_inst. I changed it to character(len=9) :: moz_var_suffix = '', which worked for me. I have attached my code here.

Let me know if this works or not for you, if you haven't solved the issue yet.

Hey Shreta,

I followed the steps you suggested because I got the same error. After editing the "mo_mozart_lib.f90" also, the error persists. I am attaching the log file along with mozbc.inp and mo_mozart_lib.f90. Can you please have a look at it? 

Thanks and Regards,

Hi there,

Instead of editing the fortran code, try adding the following line to the mozbc.inp file:

moz_var_suffix = ''  

(those are 2 single quotes)

I have this line just after moz_dir is defined.

Hello Mary,

Editing mozbc.inp file worked.

Thank you
