In ibarraespinosa/eixport: Export Emissions to Atmospheric Models

Combine total/spatial/temporal/split and write emission to file

Description

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

Usage

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

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
