chirps 2.0.0 (2026-06-23)

NEW FEATURES

  • Added get_chirps_raw() to provide direct access to CHIRPS raster products as terra::SpatRaster objects without extracting values or reshaping outputs.

  • Added support for CHIRPS v3, including both daily rnl (ERA5-based) and sat (IMERG-based) products.

  • Added get_chirts_raw() to access CHIRTS-daily maximum temperature, minimum temperature, relative humidity, and heat index datasets as raster objects.

  • Added get_chirts_era5_raw() to access CHIRTS-ERA5 daily temperature datasets extending from 1980 to near-present.

  • Added support for retrieving raw climate datasets directly from Climate Hazards Center (CHC) archives through remote Cloud Optimized GeoTIFF (COG) and GeoTIFF access.

ENHANCEMENTS

  • Added raster time metadata to raw raster outputs using terra::time().

  • Improved internal URL handling for CHIRPS and CHIRTS products through version-specific data source management.

  • Expanded package documentation with dataset descriptions, references, and citation guidance for CHIRPS v3, CHIRTS-daily, and CHIRTS-ERA5 products.

INTERNAL CHANGES

  • Refactored internal raster retrieval functions to support multiple dataset versions and products through a unified architecture.

  • Improved compatibility with modern terra workflows by exposing native raster products for downstream processing with crop(), extract(), mask(), and related functions.

CRAN release: 2022-01-13

ENHANCEMENTS

CHANGES IN BEHAVIOUR

  • New argument server = is added to indicate from which server the function should send the request, either ‘CHC’ or ‘ClimateSERV’. Please use the argument server = "ClimateSERV" for backward compatibility with previous versions of the package.
  • API requests to ClimateSERV use package httr instead of curl
  • Argument operation = in get_chirps() is only required when server = "ClimateSERV"
  • Updates function as.geojson() to matches with the new requirements for ClimateSERV

CRAN release: 2020-07-03

  • rOpenSci release version

ENHANCEMENTS

chirps 0.0.8 (2020-05-22)

CHANGES IN BEHAVIOUR

  • Remove Imports of pkg ‘tibble’ which was basically to provide a “cool” print method.
  • A new print() method is added for objects that inherits the class ‘chirps_df’
  • Pkg ‘methods’ was moved from Imports to Depends
  • Comments/suggestions given by Jake Zwart in rOpenSci pkg review are added

chirps 0.0.6 (2020-01-29)

ENHANCEMENTS

  • Comments/suggestions given by Claudia Vitolo in rOpenSci pkg review are added
  • dataframe_to_geojson(), sf_to_geojson() are added as exported functions avoiding chirps:::
  • documentation for tapajos is given avoiding chirps:::

chirps 0.0.5 (2020-01-09)

ENHANCEMENTS

  • Fix comments given by good practice goodpractice::gp(). Avoid long code lines, it is bad for readability. Avoid 1:length(…), 1:nrow(…), 1:ncol(…), 1:NROW(…) and 1:NCOL(…) expressions. Not import packages as a whole, as this can cause name clashes between the imported packages.

chirps 0.0.4 (2020-01-03)

NEW FEATURES

  • S3 methods for objects of class “geojson” in get_chirps() and get_esi()

  • Package vignette

  • Prepare for submission to ropensci

ENHANCEMENTS

  • Validations in internal functions to transform ‘sf’ into geojson

  • Add properties features to geojson output in get_chirps() and get_esi() via .add_geojson_properties()

chirps 0.0.3 (2019-12-31)

NEW FEATURES

  • get_esi is added to retrieve Evaporative Stress Index with S3 methods for “data.frame” and “sf”

  • S3 methods for objects of class “data.frame” and “sf” in get_chirps

CHANGES IN BEHAVIOUR

  • .get_request_progress and a while condition are added to check the progress of large requests and prevent the function to fail.

  • .GET is added as a general function to retrieve other datasets from ClimateSERV

  • improvements in internal functions documentation

chirps 0.0.2 (2019-12-05)
