In retostauffer/Rmosmix: Package for Downloading Public DWD MOSMIX Weather Forecasts

R Package for Downloading and Handling DWD MOSMIX Forecasts

The german weather service (DWD) publishes a set of automated weather forecasts (MOS forecasts) as publicly available data sets.

• DWD open data server
• DWD copyright information
• DWD MOSMIX product information

This small working package allows to easily download and decode these forecasts. The forecasts become available several times a day, XML format. The mosmix R package provides the following features:

• Check files available on the server
• Automatically download and parse forecasts for a set of user-defined locations
• Returns convenient time series objects
• Write (subsetted) data sets to local ASCII files

Allows to download MOSMIX-L (4x daily, 115 parameters, up to 240 hours ahead) and MOSMIX-S (24x daily, 40 parameters, up to 240 hours ahead).

For the decoding of the data sets this package depends on the XML package. Plesae note that, to be able to install the R package, libxml has to be installed. The forecasts are time series data wherefore this package also depends on the R package zoo.

Package Status

Please note that this is a working package and was written in less then a day! Should be seen as an early beta version. Feel free to use, reuse, improve and contribute!

All best,

Reto

Package Installation

mosmix can be installed using the R package githubinstall (or devtools, or simply clone and install locally).

with devtools via https (devtools::install_github)

Currently the package is only available via github. One convenient way to install packages from github is is via devtools (requires R package devtools to be installed; if not use install.packages("devtools")).

The following snippet installes the latest development version of the mosmix package from github.com/retostauffer/Rmosmix:

# Load devtools
library("devtools")

# Install package, should also resolve the dependencies
install_github("retostauffer/Rmosmix")

Note: If you do not like experimental versions feel free to install one of our release candidates, e.g., v0.0-2, an early alpha release from December 2018. To install a release candidate provide the additional ref argument. A list of available release candidates can be found on the github release page.

# Load devtools
library("devtools")

# Install package, should also resolve the dependencies
devtools::install_github("retostauffer/Rmosmix", ref = "v0.0-2")

devtools by cloning the repository

You can also clone the repository and install the package based on the checkout. For linux users:

# Change directory
cd <somewhere/on/your/local/disc>

# Clone repository
git clone https://github.com/retostauffer/Rmosmix.git

# Start R
R

As soon as you are in the interactive R shell:

# Loading the devtools library
library("devtools")

# Install package
devtools::install("Rmosmix")

Via console

Or of course via console:

# Change directory
cd <somewhere/on/your/local/disc>

# Clone repository
git clone https://github.com/retostauffer/Rmosmix.git

# Feel free to use on of our release candidates which
# might miss some features, but might also be more stable.
# A list of release candidates can be found on:
# - https://github.com/retostauffer/Rmosmix/releases
(cd Rmosmix && git checkout tags/<tagname> && cd ..)

# Install directly
R CMD INSTALL Rmosmix

# OR
R CMD build Rmosmix
