Read CHIRPS daily precipitation from Google Earth Engine

Reads UCSB-CHG/CHIRPS/DAILY (Climate Hazards Group InfraRed Precipitation With Station Data) from Google Earth Engine. Returns a terra::rast() SpatRaster with precipitation in mm/day.

Usage

read_chirps(
  date,
  region,
  backend = c("rest", "rgee"),
  cache = TRUE,
  max_tries = 3L,
  initial_delay = 1
)

Arguments

date

Character or Date. Date in "YYYY-MM-DD" format.

region

An sf::sf, sf::st_sfc(), or terra::ext() object defining the spatial extent. Required.

backend

Character. "rest" (default) or "rgee".

cache

Logical. Use disk cache? Default TRUE.

max_tries

Integer. Retry attempts. Default 3L.

initial_delay

Numeric. Initial retry delay in seconds. Default 1.

Value

A terra::rast() SpatRaster. CRS: EPSG:4326. Values: precipitation in mm/day.

Data availability

1981-01-01 to near-present. Daily. ~5.5 km spatial resolution. Coverage: 50S-50N (land only).
