Description

Add values to a variable in a netCDF file, the main use is to combine different emissions like top-down emission (EmissV emissions) and inventary emission (sush as EDGAR, GAINS, RETRO, etc).

Usage

wrf_add(file = file.choose(), name = NA, POL)

Arguments

name	name of the variable (any variable)
POL	variable to be written

Examples

{
# create the folder and emission file
dir.create(file.path(tempdir(), "EMISS"))
wrf_create(wrfinput_dir = system.file("extdata", package = "eixport"),
           wrfchemi_dir = file.path(tempdir(), "EMISS"))

# get the name of created file
files <- list.files(path = file.path(tempdir(), "EMISS"),
                    pattern = "wrfchemi",
                    full.names = TRUE)

# open, put some numbers and write
CO <- wrf_get(file = files[1], name = "E_CO")
CO[] = rnorm(length(CO),mean = 5,sd = 1)
wrf_put(file = files[1], name = "E_CO", POL = CO)
# open, put some different numbers and write
CO[] = rnorm(length(CO),mean = 10,sd = 1)
wrf_add(file = files[1], name = "E_CO", POL = CO)
}
