## Introduction to {getCRUCLdata}
The {getCRUCLdata} package provides functions that automate importing CRU CL v. 2.0 climatology data into R, facilitate the calculation of minimum temperature and maximum temperature, and formats the data into a data frame or a [base::list()] of [terra::rast()] objects for use.
CRU CL v. 2.0 data are a gridded climatology of 1961-1990 monthly means released in 2002 and cover all land areas (excluding Antarctica) at 10 arc minutes (0.1666667 degree) resolution.
For more information see the description of the data provided by the University of East Anglia Climate Research Unit (CRU), .
## Changes to original CRU CL v. 2.0 data
This package automatically converts elevation values from kilometres to metres.
This package crops all spatial outputs to an extent of ymin = -60, ymax = 85, xmin = -180, xmax = 180.
Note that the original wind data include land area for parts of Antarctica.
# Quick Start
## Install
{getCRUCLdata} is not available from CRAN.
You can install it from GitHub as follows.
``` r
if (!require("remotes")) {
install.packages("remotes")
}
install_github("ropensci/getCRUCLdata", build_vignettes = TRUE)
```
Or you can install it from the rOpenSci Universe.
``` r
# Enable the rOpenSci universe
options(repos = c(
rOpenSci = "https://ropensci.r-universe.dev",
CRAN = "https://cloud.r-project.org""))
# Install the package
install.packages("getCRUCLdata")
```

> **ABSTRACT:** We describe the construction of a 10-minute
> latitude/longitude data set of mean monthly surface climate over
> global land areas, excluding Antarctica. The climatology includes 8
> climate elements - precipitation, wet-day frequency, temperature,
> diurnal temperature range, relative humidity,sunshine duration, ground
> frost frequency and windspeed - and was interpolated from a data set
> of station means for the period centred on 1961 to 1990. Precipitation
> was first defined in terms of the parameters of the Gamma
> distribution, enabling the calculation of monthly precipitation at any
> given return period. The data are compared to an earlier data set at
> 0.5 degrees latitude/longitude resolution and show added value over
> most regions. The data will have many applications in applied
> climatology, biogeochemical modelling, hydrology and agricultural
> meteorology and are available through the School of Geography Oxford
> (), the International Water Management
> Institute “World Water and Climate Atlas” () and
> the Climatic Research Unit ().
