Re: AOD>0 with aerosol radiative feedback off

Hi,

Which variable is > 0? Is this calculated from EXTCOEF? Is aer_op_opt > 0 ?

Re: real.exe segmentation fault with complex chemistry (112-mozcart or 132-CB05 with MADE)

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: WRF-Chem RADM2 with MADE/SORGAM option with wet scavanging

Hi Pradeep,

You should be able to use the same emiss_opt and emiss_inpt_opt as in RADM, i.e., 3 and 1, respectively.

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 : ...

Re: WRF-Chem RADM2 with MADE/SORGAM option with wet scavanging

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 ...

Re: real.exe segmentation fault with complex chemistry (112-mozcart or 132-CB05 with MADE)

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.

Re: WRF stops immediately..Help!

Hi, EBU_IN are the bb emissions that are read in from the wrffirechemi file. EBU are the actual emissions used after plumerise is invoked if you are using it (i.e. 2D vs. 3D). If you would like to output that array, you will need to add "ebu_xyl" to the bb==1 package and again either add an "h" to t...

Sure, lets say you wanted to add the variable "ebio_iso" to the output. 1. Create a plain text file in your run directory named "my_iofields_list.txt" that contains the single line: +:h:0:ebio_iso 2. in the time_Control namelist, add the following line: iofields_filename = "./my_iofields_list.txt" T...

Can you please attach your rsl.out/error.0000 file for a run with debug_level > 100?

Please also make sure there are not different error messages for different processors/rsl. files

If it still is not working after a "./clean -a", instead of changing the registry, try using a my_iofields file, described in the WRF documentation.

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.

Yes, execution time will be linear, and in general, so will output size/disk space requirements.

Ok I understand - a couple ways you can do this (PH + PHB)/9.81 = geopotential height or use a simple ncl function: https://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_getvar.shtml (variable, "z") e.g., begin ; function wrf_user_getvar ( ; file_handle : file or list, ; variable : string, ; ...

Re: WRF-Chem injection heights emissions

Hi Catalina,

I think I understand the problem now - EDGAR/HTAP emissions are only a single (surface) layer, correct? Without additional information, anthro_emis will not know how to allocate the emissions vertically.

Re: WRF-Chem injection heights emissions

Hi Catalina,

The namelist option you are looking for is "kemit" in the &chem namelist. Try setting that and see what happens. As for your question (2) about the vertical levels -I'm not familiar w/ anthro emis, do you supply program with the wrfinput file?
