Missing sample prepmegan4cmaq.ef.inp in MEGANV3.2 preprocessor

I want to run MEGANV3.2 preprocessor to make “.csv” files for running MEGAN txt2ioapi. The sample prepmegan4cmaq.lai/growthform/ecotype/cantype.inp are under MEGAN32_Prep_Code_Jan_2022. However, prepmegan4cmaq.ef.inp couldn’t be found. Can someone provide this file?

Hi Runyu,

Are you trying to create the emission factor (EF) csv file? That’s done with a different tool that’s python based. Look for the Emission Factor Processor section on this page: UCI BAI - MEGAN32

You can contact me at willison.jeff@epa.gov for further assistance with MEGAN 3.2.

Thanks Willison, I have successfully run MEGAN V32 EFP and produced OutputGridEF.csv. Is it correct to change only the scen_name in the MEGAN_EFP.py script and leave the rest settings as default?

Great! I don’t think it requires any additional configuration. It just needs to point to the grid_ecotype and grid_growth_form csv files for your domain (scen_name).

Hi jeff,

I have run MEGANV32 txt2ioapi module to output the EFMAP, LAI and LDF.ncf files but no CT3.nc file under specific output directory were acquired. I found the final CANTYPFILE were under MEGANV32/work/ . Here’s my run.txt2ioapi.v32.csh and log file. Thanks for your kind attention to fix this error.

It’s an issue with the run script they distribute. Try setting:
