merge_emission: Function to merge two different emissions

In Schuch666/hackWRF: Functions to Work with WRF, NetCDF and Model Evaluation

Function to merge two different emissions

Description

Merge different emissions, the main emission or background emission (usually from a global inventory) and an auxiliary emission. The resulting emissions has the values of the auxiliar emissions for grid points with emissions and background emission for grid points with zero emissions.

Usage

merge_emission(
  background,
  auxiliar,
  output = NA,
  name,
  coef_backgroud = 1,
  coef_auxiliar = 1,
  aux_n2 = NA,
  coe_n2 = 1,
  plot = T,
  verbose = T,
  ...
)

Arguments

background	main input file (WRF-Chem emission file)
auxiliar	auxliar input file (WRF-Chem emission file)
output	output file (WRF-Chem emission file), or NA to return the emission array
name	variable/pollutant name
coef_backgroud	coefficient to multiply main input
coef_auxiliar	coefficient to multiply auxliar input
aux_n2	extra auxliar input file (will be merged with auxliar)
coe_n2	coefficient for to multiply extra auxliar input
plot	to plot from output file
verbose	display additional information
...	param for plot function

Value

if output is NA, returns an array or a matrix
