convert emiss error


New member
Hi WRF Chem community

I am trying to run the exe002 from the WRF tutorial. I am using the latest WRF version 4.4.1, and I generated the following files through PREP_CHEM_SRC V 1.5

I checked them in the grads which shows that the emissions and I have linked them correcty to the WRF run directory. I am getting the errors in the attached rsl files while running the convert_emiss utility. I am also attaching my namelist. input for convenience. Please note that I found no errors when the convert_emiss utility was compiled

The convert_emiss utility has not been well managed over the past several WRF versions. I recommend to try using an older version of the code for the convert_emiss program (e.g., v3.6.1 from here: WRF Download).

Hi Jordan
It took a long way to install WRF V 3.6.1 and along side the convert_emiss utility however I am still getting the exact same error. I am not sure what could be the problem.
I would request @kwerner to at least update the files provided on the ftp server
The files are missing or misplaced for most of the exercises only few files are present in the link added to the tutorial and even these donot have the namelist.input
Hi Jordan
thanks for the reply. Please see my attached namelists for both exercises. Kindly note that p_top_requested had to be increased from 5000 to 10000 to let real run as otherwise it gives an error. The exercise 2 also suggests to use the wrfinput and boundary file from exercise 1.

Hi Jordan

Do you have an idea of what might be going wrong here ? I have been going around in circles for almost a month now.
I also tried to use anthro_emiss utility but it seems like it is only suitable for anthropogenic emissions from EDGAR.
