Re: Problem running CBMZ-MOSAIC (4 bins) with AFWA dust scheme

Hi Rui, Unfortunately neither of the GOCART based dust schemes are properly coupled to MOSAIC aerosol schemes. For example, look at lines 303-326 in chem/module_gocart_dust_afwa.F Note that there are only a few cases where the 5 size bins of dust emissions (tc) are added to the chem array. For CB05_...

Re: WRF-Chem 4.3 crash

HI,

Can you try turning off emissions? I'm wandering about this line in your logs:

mediation_integrate: med_read_wrf_chem_emissions: Open file wrfchemi_d01_2018-04-07_00:00:00
d01 2018-04-07_00:00:00 Error trying to read metadata

I don't think that is the reason but please double check.

Re: WRF-Chem Compilation Error

Hi,

Yes the "Killed" message in your log indicates a memory error unfortunately. If you are not going to be using CLM, you can delete this from your configure file and try again - "-DWRF_USE_CLM"

Re: error: This option is not recognized: _real

Hi,

Typically wrf.exe is compiled with: ./compile em_real

If you want to compile the convert emiss program, you need to specify that. I.e., given the compile program downloaded from the link, you would specify:

./compile emi_conv

Re: Dificulty in installing prep_chem_sources-1.8.3

Hi all, Unfortunately the WRF-Chem team does not manage the prep chem package. I notice you are using v1.8.3, however, based on their website: Please notice PREP-CHEM-SOURCES is in Beta stage and could not work as expect Have you tried using an earlier version or contacting the prep-chem developers?...

Re: Sea-salt emissions with chem_opt=9 or chem_opt=11

Hi,

Note that seas_opt is not the same as seasalt_emiss_active. See this line(s) In emissions_driver.F :

if(config_flags%seas_opt == 2 )seasalt_emiss_active = 1

So setting seas_opt = 2 should work for both. I'm looking at 3.9.1.1.

Re: Sea-salt emissions with chem_opt=9 or chem_opt=11

Hi Rui, I'm looking at WRF v3.9.1.1 and see that you still should be able to use seas_opt = 2 despite what the UG says. HOWEVER, it is possible there are errors associated with the scheme and thus not recommended. In the code, it lists: ! William.Gustafson@pnl.gov; 10-May-2007. as the developer but ...

Re: AOD>0 with aerosol radiative feedback off

Hi,

The aerosols will be invisible to radiation with aer_ra_feedback = .false., and the tauaer* variables will still be calculated with aer_op_opt > 0 but will not be applied. You should be able to verify this by switching aer_ra_feedback = .true. and seeing the differences in swdown.
