era5_to_monthly_cpp: Unified ERA5-Land hourly-to-monthly aggregation

In xbioclim: Bioclimatic Variables from Monthly Climate Data

Unified ERA5-Land hourly-to-monthly aggregation

Description

Converts hourly 2-m temperature and total precipitation to the four CHELSA-compatible monthly climate variables in a single parallel pass.

Usage

era5_to_monthly_cpp(
  hourly_t2m,
  hourly_tp,
  n_days,
  to_celsius = FALSE,
  ncores = 1L
)

Arguments

hourly_t2m	Numeric matrix (n_pixels x n_hours_t2m): hourly 2-m temperature in Kelvin. n_hours_t2m must equal 24 * n_days.
hourly_tp	Numeric matrix (n_pixels x n_hours_tp): hourly total precipitation in metres. n_pixels must match hourly_t2m.
n_days	Integer: number of days in the month.
to_celsius	Logical: convert temperatures from Kelvin to Celsius? Default FALSE.
ncores	Integer: number of OpenMP threads (default 1).

Value

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