Package 'rchelsa'

Access high resolution climate data for Europe.

Description

Access high resolution climate data for Europe.

Usage

chl_europ_obs(period = "year", var, year, path = ".")

Arguments

period	time period (see below) or "doc" for documentation.
var	variable name (see XXX).
year	year only available when period is set to 'daily' or 'yearly'.
path	path to the folder where files will be stored.

Details

Time periods (periods) are as follows:

• daily: Data files on a daily resolution (usually years available are 1981-2005)

• yearly: Annual aggregations of a variable (usually years available are 1981-2005).

• monthly: Data files on a monthly resolution.

• normal: Long term, climatological, means of a variable over a Normals period.

Access CHELSA timeseries

Description

Access CHELSA timeseries

Usage

chl_ts(var, year, val = NULL, path = ".")

Arguments

var	variable name.
year	year.
val	optional.
path	path to the folder where files will be stored.

Details

"The CHELSA timeseries data consists of monthly downscaled model output temperature and precipitation estimates at a horizontal resolution of 30 arc sec. from 1979-2013. The resulting data consist of a mean monthly temperature and precipitation amounts." (Karger et al. 2017)
