In xbioclim: Bioclimatic Variables from Monthly Climate Data

Aggregate ERA5-Land hourly 2-m temperature to monthly statistics

Description

Converts an hourly temperature matrix to monthly mean temperature (tas), monthly mean of daily maxima (tasmax), and monthly mean of daily minima (tasmin), following the CHELSA variable convention.

Usage

era5_t2m_to_monthly_cpp(hourly, n_days, to_celsius = FALSE, ncores = 1L)

Arguments

hourly	Numeric matrix (n_pixels x n_hours): hourly 2-m temperature. Column-major layout. n_hours must equal 24 * n_days.
n_days	Integer: number of days in the month.
to_celsius	Logical: if TRUE, convert Kelvin to Celsius (default FALSE, output in Kelvin matching CHELSA convention).
ncores	Integer: number of OpenMP threads (default 1).

Value

A named list with three numeric vectors of length n_pixels: tas, tasmax, tasmin.
