Convert_emiss

Postby phayes » Wed Oct 29, 2008 4:52 pm

I would be truly grateful if someone could respond on how to go from the emiss_v03.F program to the final data format needed to run the WRF Chem. I have a triple nested grid and have already created three sets of files for each domain using the emiss_v03.F program. I end up with wrfem_00to12Z_d01 and wrfem_12to24Z_d01. I am a bit confused after this. I compiled the conv_emiss and have a convert_emiss.exe file in my chem directory. Once I run this though, I get errors of:

Namelist dfi_control not found in namelist.input. Using registry defaults for v
ariables in dfi_control
-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE: module_dm.b LINE: 126
WRF_DM_INITIALIZE (RSL_LITE): nproc_x * nproc_y in namelist ne 1


I am not sure if I am missing a step. I appreciate the help!!!

Do you have the number of processors in x and y specified?
The error suggest something is wrong with what you specified for nio_groups possibly...

I also have a convert_emiss problem. Please help me!
I use the global emission data with 2 domains. The files generated by prep_chem_sources were linked to test/em_real as follows:
**-g1-ab.bin ---->emissopt3_d01
**-g1-bb.bin ---->emissfire_d01
**-g1-gocartBG.bin ---->wrf_gocart_backg
**-g2-ab.bin ---->emissopt3_d02
**-g2-bb.bin ---->emissfire_d02
**-g2-gocartBG.bin ---->wrf_gocart_backg_d02

After I ran convert_emiss.exe, wrfchemi_d01 and wrfchemi_gocart_bg_d01 were created only. Why the files of wrfchemi_d02 and wrfchemi_gocart_bg_d02 were not generated? Does the files are not necessary?
Thank you for your attention!

Well I am replying to your post 3 1/2 years late, so hopefully you are not still sitting at your computer waiting for a reply. However I came across this post in search of an answer to a related question and thought I shoud post what I do know, in case someone with the same issue stumbles across this thread.

According to the WRF-Chem Users Guide (V3.5 - likely same for V3.6) convert_emiss.exe cannot handle generating nested domains. To achieve what you want (or should I say wanted 3 1/2 years ago) you need to run convert_emiss.exe as if each domain were the top-level (mother) domain. There is a description (if you want to call it that :? ) of how to do this on p.32 of above noted user's guide. Trying to follow that description is where I got stuck because no matter what I try I can't seem to trick convert_emiss.exe into handling my nested domain data properly.

The documentation is reeeally poorly written for nearly everything regarding the creating-your-own-emissions part of the deal.
Anyway, in case anybody wants, I have written a script in python that successfully creates the wrfchemi,wrffirechemi and wrfchemi_gocart input files for as many grids as necessary. Just send me a message and I'll give it to you.

Best regards,

Dear WRF-Chem users,

I have generated three *.bin files using prep_chem_sources and linked them according to the manual, namely
test1.0.0-T-2013-07-28-000000-g1-ab.bin -> emissopt3_d01
test1.0.0-T-2013-07-28-000000-g1-bb.bin -> emissfire_d01
test1.0.0-T-2013-07-28-000000-g1-gocartBG.bin -> wrf_gocart_backg

Upon convert_emiss.exe execution I received the following message:
[mahally@nova test01]$ ./convert_emiss.exe

which is long enough so that gocart background data should need be updated (ie. initial time data should be enough) to run a five day simulation.
Any help?

Sir,

I've meet the same problem. Could you please give your script of creating own emissions, thanks~ :D

Is there any step by step guide to create wrfchemi? Maybe from emission data, and then to ".bin" data, and then run convert_emiss?? I can't find that guide

I've been able to use ArcMap to convert the emissions into a netcdf file and it works when placed into WRF-Chem. Do I need to be concerned that it might not be mapped correctly?

Hi, can you please share with me your python script. I've been stuck with creating wrfchemi files using convert_emiss.

Thanks!
