The process_terraclimate() function imports and cleans climate and water balance data, returning a single SpatRaster object.

Usage

process_terraclimate(
  date = c("2023-09-01", "2023-09-10"),
  variable = NULL,
  path = NULL,
  extent = NULL,
  ...
)

Arguments

date: character(1 or 2). Date (1) or start and end dates (2). Format YYYY-MM-DD (ex. September 1, 2023 = "2023-09-01").
variable: character(1). Variable name or acronym code. See TerraClimate Direct Downloads for variable names and acronym codes.
path: character(1). Directory with downloaded netCDF (.nc) files.
extent: numeric(4) or SpatExtent giving the extent of the raster if NULL (default), the entire raster is loaded
...: Placeholders.
