parameter setting in set_prepchem_input.sh #13

Closed yliu-yb closed 4 months ago

yliu-yb commented 4 months ago

I found that the set_prepchem_input.sh script does not modify the following parameters, but these parameters in prep_chem_sources.inp provided on GitHub are not the default values. Parameters in prep_chem_sources.inp : nlat, lon_beg, lat_beg, delta_lon, delta_lat. Do we need to manually modify these parameters?

The default values: nlat=320, ! if gg (only global grid) lon_beg = -180., ! (-180.:+180.) long-begin of the output file lat_beg = -90., ! ( -90.:+90. ) lat -begin of the output file delta_lon = 360, ! total long extension of the domain (360 for global) delta_lat = 180, ! total lat extension of the domain (180 for global)

The parameters in your GitHub are： nlat=192, ! if gg (only global grid) lon_beg = 50, ! (-180.:+180.) long-begin of the output file lat_beg = 30, ! ( -90.:+90. ) lat -begin of the output file delta_lon = 120., ! total long extension of the domain (360 for global) delta_lat = 70., ! total lat extension of the domain (180 for global)

Not all parameters in prep_chem_sources.inp are needed to be modified. Actually the script set_prepchem_input.sh assumes that the grid projection is Lambert. So the parameters which are not related to this projection (e.g. global grid) are not modified.

I just looked at the documentation, and different projections correspond to different grid settings. Thank you very much!

I've been following the tutorial you posted on YouTube, and I encountered an error when running convert_emiss.exe. I've been unable to resolve it and hope to get your help.

I successfully ran convert_emiss after updating WRF from version 3.9.1 to 4.6. Thank you very much!
