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 )
| 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 |
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
