Create day length rasters — create_daylength_rst • barrks

Generate a multi-layer SpatRaster of day lengths for a given template. The package geosphere is required to use this function.

Usage

create_daylength_rst(
  template,
  dates = terra::time(template),
  crs = "EPSG:4258",
  .quiet = FALSE
)

Arguments

template: (Multi-layer) SpatRaster that determines the spatial extent of the result.
dates: Dates that should be processed. If not specified, the dates of template are used through terra::time().
crs: Coordinate reference system with longitude/latitude metrics. It is used to project the raster coordinates to be able to retrieve the latitude.
.quiet: If TRUE, messages are suppressed.

Value

A multi-layer SpatRaster. Each layer represents one date.

Examples

# \donttest{
# calculate day length, use barrks_data()$tmin as template
dl <- create_daylength_rst(barrks_data()$tmin, .quiet = TRUE)

# plot day length on May 1st, 2015
terra::plot(dl[[terra::time(dl) == '2015-05-01']])

# }
