xbioclim: Bioclimatic Variables from Monthly Climate Data

Computes the 19 standard bioclimatic variables (BIO01-BIO19) from monthly climate data. The variable set was originally proposed by Nix (1986, ISBN:978-0-644-04887-3) for the BIOCLIM modelling system and is also distributed with the CHELSA climatologies (Karger et al., 2017 <doi:10.1038/sdata.2017.122>). Provides both individual variable functions and a unified interface to compute all 19 variables at once. Designed as an R implementation of the 'xbioclim' C++ library (Robles Fernandez, 2026 <https://github.com/alrobles/xbioclimcpp>). Supports single-pixel vectors and block-based raster processing via 'terra' for memory-efficient handling of large spatial datasets. Includes helpers to transform ERA5-Land hourly reanalysis data (Muñoz-Sabater et al., 2021 <doi:10.5194/essd-13-4349-2021>) into monthly climate inputs.
