chirps: API Client for CHIRPS and CHIRTS
Overview
chirps provides the API Client for the Climate Hazards Center 'CHIRPS' and 'CHIRTS'. The 'CHIRPS' data is a quasi-global (50°S – 50°N) high-resolution (0.05 arc-degrees) rainfall data set, which incorporates satellite imagery
and in-situ station data to create gridded rainfall time series for trend analysis and seasonal drought monitoring. 'CHIRTS' is a quasi-global (60°S – 70°N), high-resolution data set of daily maximum and minimum temperatures. For more details on 'CHIRPS' and 'CHIRTS' data please visit its official home page https://www.chc.ucsb.edu/data.
Quick start
From CRAN
The stable version is available through CRAN.
install.packages("chirps")
From GitHub
A development version that may have new features or bug fixes is available through GitHub.
library("remotes")
install_github("ropensci/chirps", build_vignettes = TRUE)
Example
Fetch CHIRPS data from three points across the Tapajós National Forest (Brazil) from in Jan-2017. The default procedure will download the COG files from the CHIRPS server and handle it internally using the package terra. This is more interesting when dealing with hundreds of points and days. Data can be returned as a matrix using the argument as.matrix = TRUE.
library("chirps")
lonlat <- data.frame(lon = c(-55.0281,-54.9857, -55.0714),
lat = c(-2.8094, -2.8756, -3.5279))
dates <- c("2017-01-01", "2017-01-31")
dat <- get_chirps(lonlat, dates, server = "CHC", as.matrix = FALSE)
For a faster download of few datapoints (~ 10 datapoints), the argument server = "ClimateSERV" can be used
library("chirps")
lonlat <- data.frame(lon = c(-55.0281,-54.9857, -55.0714),
lat = c(-2.8094, -2.8756, -3.5279))
dates <- c("2017-01-01", "2017-01-31")
dat <- get_chirps(lonlat, dates, server = "ClimateSERV", as.matrix = FALSE)
Going further
The full functionality of chirps is illustrated in the package vignette. The vignette can be found on the package website or from within R once the package has been installed, e.g. via:
vignette("Overview", package = "chirps")
Use of CHIRPS data
While chirps does not redistribute the data or provide it in any way, we encourage users to cite Funk et al. (2015) when using CHIRPS and Funk et al. (2019) when using CHIRTS
