"Now just download the wrfchemi and wrfbdy from server (if using one) and extract the lat/long of the node points. Write a code to replace EDGAR/RETRO emisions of your pollutant from your wrfchemi with emisions from your shapefile. "
I see that I can create a shapefile of my emissions and write a program to replace the EDGAR/RETRO emissions.
now, I do have these 2 with me; however, how do I go upon replacing the EDGAR/RETRO emissions?
Is there a way to interpolate the shapefile with its emissions attributes to the netcdf file (wrfchemi)?
How do I go about writing the code to copy the shapefile attributes to the wrfchemi file? The shapefile certainly needs to be disaggregated to the grids in the netcdf file, but I am not sure how to do this yet.

Hoping someone could help me with this.
