Functions to write grid meteorological data to the file system.

writemeteorologygrid(object, file, dates = NULL, format = "netCDF", 
                     byPixel = FALSE, chunksizes = NA, add = FALSE, overwrite = FALSE, 
                     verbose = FALSE)
writeemptymeteorologygrid(file, grid, proj4string, dates, 
                     byPixel = FALSE, chunksizes = NA, overwrite = FALSE, 
                     verbose = FALSE)
writemeteorologypixels(object, file, dates = NULL, format = "netCDF", 
                       byPixel = FALSE, chunksizes = NA, add = FALSE, overwrite = FALSE, 
                       verbose = FALSE)
writemeteorologygridpixel(file, index, data, verbose = FALSE)

Arguments

object

An object of class SpatialGridMeteorology-class or class SpatialPixelsMeteorology-class with the meteorological data to be written.

file

A string with the file name to be written.

dates

A Date vector object or a character string indicating the dates to be written.

format

Format of meteorological data. The only accepted format is "netCDF".

byPixel

Boolean flag to specify whether file will be written/read by pixels. This forces a different (suposedly) more efficient chunking based on time series data instead of daily grids.

chunksizes

Specifies the size of data chunks to be read/written. If set, this must be a vector of three integers corresponding to XYT.

add

Boolean flag to indicate that NetCDF exists and data should be added/replaced.

grid

An object of class GridTopology-class

proj4string

Object of class CRS.

overwrite

Boolean flag to force overwriting an existing NetCDF.

verbose

A logical flag to output process information in the console.

index

Integer indicating the grid index position to be written.

data

A data frame with meteorological data corresponding to a pixel.

Details

Functions writemeteorologygrid and writemeteorologypixels writes grided meteorological data (i.e. class SpatialGridMeteorology-class or class SpatialPixelsMeteorology-class, respectively) into a netCDF, with the possibility to overwrite existing data. Function writemeteorologygridpixel is meant to add/replace data in a netCDF corresponding to a specific pixel identified by its grid index. Function writemeteorologygrid creates an empty netCDF with the specified grid dimensions, coordinate reference system and dates.
