Overview

A package to make life easier working with daily netcdf files from the EURO-CORDEX RCMs. Relies on data.table to do the heavy data lifting.

Main components:

• extract single grid cells (e.g. for stations) from rotated pole grid: rotpole_nc_point_to_dt()
• extract the whole array of a variable in long format: nc_grid_to_dt()
• can deal with non-standard calendars (360, noleap) and interpolate them
• get and check list of EURO-CORDEX .nc files: get_inventory()

Alternatives:

The stars and terra (previously raster) packages can be used similarly, although the functionality for rotated pole grids and non-standard calendars might be different.

Installation

Get the CRAN version:

# from CRAN
install.packages("eurocordexr")

Or get the latest (development) version from github:

# or from github
devtools::install_github("mitmat/eurocordexr")

Requires the following packages (which should be installed automatically with above):

library(data.table)
library(lubridate)
library(magrittr)
library(ncdf4)
library(ncdf4.helpers)

For the netCDF packages, depending on your system, additional libraries might be needed.

Some documentation can be found in the doc/ subfolder. To view the HTML files you may need to download the files (and not view them in github).
