mozbc error when checking dust data in mozart data with MOZART + MOSAIC 4 bins

[ying...@sjsu.edu]

Hello, I use WRF-Chem with MOZART+MOSAIC 4BINS,  Chem_opt = 201. mozbc is compiled well. 

But when I run it with  CBMZ-MOSAIC_4bins.inp, error shows when checking wrf variable num_a01: chk_moz_vars: could not find .93e17*[ (attached: mozbc.out), I notice this is a multiplier problem and tried to fix this by replacing 0.5*3.93e17*[DUST1] by 1.965e17*[DUST1]. 

And did the similar modification for num_a02, However, the error msg changes to :chk_moz_vars: could not find _VMR_inst.(attched: mozbc_js.out) 

"_VMR_inst" is the suffix of moz_var, I check the Mozart data I downloaded and find the variables DUST[1-4] don't have _VMR_inst as suffix (attached:head_h0001.out).

Anyone has idea about fixing this problem? Thank you very much!

Hi Ying Song,

​the problem is that the lines are too long for the length the string is defined in the Fortran Code. You could change the mozbc code or simply shorten the lines. I attach the assignment for the num species below, which should work when included in your mozbc.inp file. Note that this is following the suggested assignment from the MOZART-MOZAIC User Guide (https://www2.acom.ucar.edu/sites/default/files/wrf-chem/MOZART_MOSAIC_V3.6.readme_dec2016.pdf)

Thanks, Gabi!

mozbc works fine now by following your suggestion.
