bioclim_rolling: Rolling optimal-window bioclimatic variables

In xbioclim: Bioclimatic Variables from Monthly Climate Data

Rolling optimal-window bioclimatic variables

Description

Computes the 19 bioclimatic variables using a rolling window of arbitrary length over the full 12 months. The base variables (bio01..bio07, bio12..bio15) are annual, while the rolling variables (bio08..bio11, bio16..bio19) use the best window-month period. With window = 3 this is equivalent to the standard BIO08-BIO19.

Usage

bioclim_rolling(tas, tasmax, tasmin, pr, window = 3L, na.rm = FALSE, ...)

Arguments

tas	Numeric vector (length 12), matrix (pixels x 12), SpatRaster with 12 layers, or BioclimData.
tasmax	Same form as tas: monthly maximum temperature.
tasmin	Same form as tas: monthly minimum temperature.
pr	Same form as tas: monthly precipitation.
window	Integer: length of the rolling window in months (2-11). Default is 3.
na.rm	Logical. If FALSE (default), a single NA makes all outputs NA for that pixel. If TRUE, missing months are skipped.
...	Not currently used.

Value

Named vector (length 19), matrix (pixels x 19), or 19-layer SpatRaster.
