Re: WRF-Chem Compilation Error

Hi,

These lines make me think it is a memory error:

Killed
Makefile:183: recipe for target 'module_state_description.F' failed

Can you increase the memory available to the compile?

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.

Hi Vinod,

I'm glad you fixed it with the intel compiler. If you could please post which versions of the gfortran and intel compilers you tested that would be helpful for users that may experience the same issues. Thanks!

Re: Issue with v3 v4 data for WRF4.2.1 and Ndown.exe

Hi Paul, I am unsure about the first part of your question - since you are creating pre-v4 data, you must set the force_use_old_data = T. As for your ndown error, it likely is coming from this namelist option: "use_theta_m" in the &dynamics namelist, which is by default = 1; i.e. the error "Error : ...

Hi Pradeep, You are correct in that 106 does not have cloud chemistry, while option 11 does. In general, KPP makes altering the chemical mechansim easier and is numerically efficient. The warning indicates that the developer cautions the use of the mechanism since it likely has not been tested over ...

Hi,

It looks like you are only running real with 1 processor? Please try running with with more (8 would be a good start). If the same error persists, please try to compile with the debug option and rerun so we can do the traceback.

Hi Rui,

The real program does read in the anthropogenic emissions - try running wrf.exe with debug level > 100 and you should see that your emissions will be read in and used.
