daymet_grid_tmean: Averages tmax and tmin 'Daymet' gridded products

In daymetr: Interface to the 'Daymet' Web Services

Averages tmax and tmin 'Daymet' gridded products

Description

Combines data into a single mean daily temperature (tmean) gridded output (geotiff) for easy post processing and modelling. Optionally a raster object is returned to the current workspace.

Usage

daymet_grid_tmean(path = tempdir(), product, year, internal = FALSE)

Arguments

path	full path location of the daymet tiles (default = tempdir())
product	either a tile number or a ncss product name
year	which year to process
internal	TRUE / FALSE (if FALSE, write the output to file) using the Daymet file format protocol.

Examples

## Not run: 
# This code calculates the mean temperature
# for all daymet tiles in a user provided
# directory. In this example we first
# download tile 11935 for tmin and tmax

# download a tile
download_daymet_tiles(tiles = 11935,
                      start = 1980,
                      end = 1980,
                      param = c("tmin","tmax"),
                      path = tempdir())

# calculate the mean temperature and export
# the result to the R workspace (internal = TRUE)
# If internal = FALSE, a file tmean_11935_1980.tif
# is written into the source path (path_with_daymet_tiles)
tmean <- daymet_grid_tmean(path = tempdir(),
                          tile = 11935,
                          year = 1980,
                          internal = TRUE)

## End(Not run)
