In EmissV: Tools for Create Emissions for Air Quality Models

Read grid information from a NetCDF file

Description

Return a list containing information of a regular grid / domain

Usage

gridInfo(file = file.choose(), z = FALSE, verbose = TRUE)

Arguments

file	file name/path to a wrfinput, wrfchemi or geog_em file
z	TRUE for read wrfinput vertical coordinades
verbose	display additional information

Value

a list with grid information from air quality model

Note

just WRF-Chem is suported by now

Examples

grid_d1 <- gridInfo(paste(system.file("extdata", package = "EmissV"),
                                      "/wrfinput_d01",sep=""))
grid_d2 <- gridInfo(paste(system.file("extdata", package = "EmissV"),
                                      "/wrfinput_d02",sep=""))
grid_d3 <- gridInfo(paste(system.file("extdata", package = "EmissV"),
                                      "/wrfinput_d03",sep=""))
names(grid_d1)
# for plot the shapes
shape   <- raster::shapefile(paste0(system.file("extdata", package = "EmissV"),
                                                "/BR.shp"))
raster::plot(shape,xlim = c(-55,-40),ylim = c(-30,-15), main="3 nested domains")
axis(1); axis(2); box(); grid()
lines(grid_d1$boundary, col = "red")
text(grid_d1$xlim[2],grid_d1$Ylim[1],"d1",pos=4, offset = 0.5)
lines(grid_d2$boundary, col = "red")
text(grid_d2$xlim[2],grid_d2$Ylim[1],"d2",pos=4, offset = 0.5)
lines(grid_d3$boundary, col = "red")
text(grid_d3$xlim[1],grid_d3$Ylim[2],"d3",pos=2, offset = 0.0)
