tempfor_from_img.nc error while running fire_emiss for FINN data

[Zhifeng Yang]

Hi

This is Zhifeng Yang, a graduate student from the department of physics, University of Maryland, Baltimore County.

I am using FINN data with the fire_emiss utility for WRF-Chem. When I set everything up and prepared the .inp file, and I ran fire_emiss, I got the following error:

wrf_file: DX =    3.00000024      km
 
 proj_init: projection =  1
 proj_init: proj%hemi    =    1.00000000   
 proj_init: proj%rebydx  =    2123.33325   
 proj_init: proj%polei,j =   -463.284729       2308.86743   
 proj_init: west-east,south-north =   255  205
 handle_ncerr: fire_srf_types: Failed to open /home/vy57456/zzbatmos_user/data/emission/smoke_emission/FINN/tempfor_from_img.nc
 No such file or directory                                                      
STOP netcdf error

I found where the error happens. It happens at the follow statement in file 'fire_srf_types.f90'

call handle_ncerr( nf_open( trim(filespec), nf_noclobber, ncid ), message )

It seems that nf_open does not open the defined file name. Also I can't find the file named tempfor_from_img.nc. I am not sure why. Any ideas?

Thank you

Zhifeng

Hi, 

it seems you have not downloaded the necessary fire_emiss input data. Please note that on the FINN download page, in order to run fire_emiss you have to download the "Utility to use the FINNv1 emissions within WRF-Chem or global (MOZART-4, CAM-Chem) simulations " as well as the "Input files for the fire emissions utility".

Hi Dr. Pfister,

Yes, you are right. I forgot to download these four files.

grass_from_img.nc  shrub_from_img.nc  tempfor_from_img.nc  tropfor_from_img.nc

Now I can generate the fire emission data for WRFChem. Thank you so much for your help.

Best,

Hi Dr. Pfister,

I looked through the FINN website and found a new data named 'ALL_Emiss_04282014.nc', which is the emission from open burning waste fire. So I downloaded into my FINN directory. However, I couldn't find code to read and process it in fire_emiss.f90 and related codes. Do you know how to use this data set? Thank you

Best,

Zhifeng

Hello Zhifeng, 

as stated in the README for this file, it represents emissions from trash burning. These should not be added to the FINN fire emissions but would rather be part of anthropogenic emissions. However, note that many anthropogenic emission inventories already include this sector.

Ok. Actually I am going to use both FINN and NEI-05 emissions in my WRFChem simulation. So in my case, I don't need to include trash burning emission, since NEI already includes this kind of emission. Thank you very much for your help and guidance. I appreciate your time and work very much.

Best,

Zhifeng
