Function to expand, split and write emissions. The input is expanded into time by profile and split between variables with diferent weights.

to_wrf(POL, file = file.choose(), name = NA, total = NA, norm = F,
  profile = 1, weights = 1, verbose = T)

Arguments

POL

matrix or array of emissions of spatial weights

file

emission file name

name

species to be write

total

total of emited species (modifier)

norm

if the spatial weights need to be normalized (modifier)

profile

temporal profile to expand the emissions (modifier)

weights

weight of each species (modifier)

verbose

display additional information

Note

length(profile) must be the number of times in the emission file (value of frames_per_auxinput5 if wrf_create() was used to create this file).

total is an additional way to calculate or correct the total emissions

sum(profile) = 1 and sum(weights) = 1 to conserve mass

names and weights must have the same length
