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", "2023-09-01"),
variable = NULL,
path = NULL,
extent = NULL,
...
)Arguments
- date
character(2). length of 10 each. Start/end date of downloaded data. 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

Placeholders.
Note
Layer names of the returned SpatRaster object contain the variable acronym, year,
and month.
TerraClimate data has monthly temporal resolution, so the first day of each month is used as a placeholder temporal value.
Examples
## NOTE: Example is wrapped in `\dontrun{}` as function requires a large
## amount of data which is not included in the package.
if (FALSE) { # \dontrun{
terraclimate <- process_terraclimate(
date = c("2023-01-01", "2023-01-10"),
variable = "Precipitation",
path = "./data/ppt"
)
} # }
