Does anybody here have any experience with editing wrfchemi outputs from the prep_chem utility so that I overwrite the file with my own emissions?
I am knowledgeable in python, but I am not that well oriented with the manipulation of NetCDF files.
What I want to do, basically, is to use my own emissions inside the WRF/Chem model
- I have a shapefile of emissions (gridded) with each grid having a value for the emissions.
- I want to convert this to a readable format for the WRF/Chem; however, I think editing the wrfchemi files by prep_chem would be easier? (Tell me if not)
I have read the emissions guide of the WRF/Chem, but it does not really expound on details about this especially about the following
- How to deal with the speciation (my shapefile has only PM10 and PM2.5). where exactly do I place this in the new emissions file (the edited wrfchemi)I want. There are many pm species there (like pm2.5 nucleation mode, pm, etc). I am not sure what weights to put on these.
- My emissions are not time dependent, and what do I do when I edit the wrfchemi file for this. (the wrfchemi files I have now are also not time dependent)
Hoping someone could help out with this.
