Arguments

wrfinput_dir

folder with the wrfinput file(s)

wrfchemi_dir

output folder

domains

domain or domains to process

frames_per_auxinput5

value from wrf &time_control namelist.input, number of times in a single emission file

auxinput5_interval_m

value from wrf &time_control namelist.input, interval in minutes between different times

day_offset

number of days (can be a fracion) to create multiple files

io_style_emissions
