MEGAN - final output issue!

[SAHIR AZMI]

My output results are quite same before using MEGAN and after its use, so I am quite in a doubt if this utility is scaling these emissions from original inventory to 2018 or not?

I want to run ./megan utiliy for 1 year from jan 2018 to dec 2018. 

My input namelist is as, is there anything else I have to write in it??

&control

domains = 1,

start_lai_mnth = 1,

end_lai_mnth   = 12,

wrf_dir   = '/scratch/sahir/largefile/WRF-Chem/WRFV3_ANTHRO/WRFV3_ANTH/run',

megan_dir = '/scratch/sahir/largefile/MEGAN'

/

I am attaching here how my MEGAN directory looks like, if anything else I have to do or install in it?

Kindly help!

Hello Sahir

I do not understand what your problem is. To run WRF-Chem with MEGAN online biogenic emissions, you have to create the static input files with the megan_bio_emiss tool. This file is being read in at the start of your simulation and biogenic emissions are calculated during runtime based on the modeled meteorology. There is no scaling from the 2013 static input data to any other year. 

Please read through the tutorial presentations for information: https://ruc.noaa.gov/wrf/wrf-chem/tutorial2018.htm
