Welcome to Wetterdienst, your friendly weather service library for Python.
We are a group of like-minded people trying to make access to weather data in
Python feel like a warm summer breeze, similar to other projects like
rdwd for the R language, which originally drew our interest in this project.
Our long-term goal is to provide access to multiple weather services as well as other
related agencies such as river measurements. With wetterdienst we try to use modern
Python technologies all over the place. The library is based on polars (we <3 pandas, it is still part of some
IO processes) across the board, uses Poetry for package administration and GitHub Actions for all things CI.
Our users are an important part of the development as we are not currently using the
data we are providing and only implement what we think would be the best. Therefore
contributions and feedback whether it be data related or library related are very
welcome! Just hand in a PR or Issue if you think we should include a new feature or data
source.
For an overview of the data we have currently made available and under which license it is published take a look at the data section. Detailed information on datasets and parameters is given at the coverage subsection. Licenses and usage requirements may differ for each provider so check this out before including the data in your project to be sure that you fulfill copyright requirements!
- APIs for stations and values
- Get stations nearby a selected location
- Define your request by arguments such as parameter, period, resolution, start date, end date
- Define general settings in Settings context
- Command line interface
- Web-API via FastAPI
- Rich UI features like wetterdienst explorer and streamlit app
- Run SQL queries on the results
- Export results to databases and other data sinks
- Public Docker image
- Interpolation and Summary of station values
Via PyPi (standard):
pip install wetterdienstVia Github (most recent):
pip install git+https://github.com/earthobservations/wetterdienstThere are some extras available for wetterdienst. Use them like:
pip install wetterdienst[http,sql]- docs: Install the Sphinx documentation generator.
- ipython: Install iPython stack.
- export: Install openpyxl for Excel export and pyarrow for writing files in Feather- and Parquet-format.
- http: Install HTTP API prerequisites.
- sql: Install DuckDB for querying data using SQL.
- duckdb: Install support for DuckDB.
- influxdb: Install support for InfluxDB.
- cratedb: Install support for CrateDB.
- mysql: Install support for MySQL.
- postgresql: Install support for PostgreSQL.
- interpolation: Install support for station interpolation.
In order to check the installation, invoke:
wetterdienst --helpDocker images for each stable release will get pushed to GitHub Container Registry.
There are images in two variants, wetterdienst-standard and wetterdienst-full.
wetterdienst-standard will contain a minimum set of 3rd-party packages,
while wetterdienst-full will try to serve a full environment, including
all of the optional dependencies of Wetterdienst.
Pull the Docker image:
docker pull ghcr.io/earthobservations/wetterdienst-standardUse the latest stable version of wetterdienst:
$ docker run -ti ghcr.io/earthobservations/wetterdienst-standard
Python 3.8.5 (default, Sep 10 2020, 16:58:22)
[GCC 8.3.0] on linuximport wetterdienst
wetterdienst.__version__The wetterdienst command is also available:
# Make an alias to use it conveniently from your shell.
alias wetterdienst='docker run -ti ghcr.io/earthobservations/wetterdienst-standard wetterdienst'
wetterdienst --help
wetterdienst --version
wetterdienst infoRunning wetterdienst on Raspberry Pi, you need to install numpy and lxml prior to installing wetterdienst by running the following lines:
# not all installations may be required to get lxml running
sudo apt-get install gfortran
sudo apt-get install libopenblas-base
sudo apt-get install libopenblas-dev
sudo apt-get install libatlas-base-dev
sudo apt-get install python3-lxmlAdditionally expanding the Swap to 2048 mb may be required and can be done via swap-file:
sudo nano /etc/dphys-swapfileThanks chr-sto for reporting back to us!
