wetterdienst 0.7.0

Python library to ease access to open weather data

Introduction

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.

While our long-term goal is to provide access to multiple weather services, we are still stuck with the German Weather Service (DWD). Contributions are always welcome!

This program and its repository tries to use modern Python technologies all over the place. The library is based on Pandas across the board, uses Poetry for package administration and GitHub actions for all things CI.

Features

Coverage

The library currently covers

• historical weather data from ground stations

• RADOLAN fitted radar data for areal precipitation

• MOSMIX statistical optimized scalar forecasts extracted from weather models

To get better insight on which data we have currently made available, with this library take a look at data coverage.

Details

• Get metadata for a set of Parameter, PeriodType and TimeResolution.

• Get station(s) nearby a selected location for a given set.

• Store/recover collected data.

• Docker image to run the library dockerized.

• Client to run the library from command line.

Setup

Run the following to make wetterdienst available in your current environment:

pip install wetterdienst

Synopsis

Get historical data for specific stations, using Python:

from wetterdienst import DWDStationRequest, Parameter, PeriodType, TimeResolution

request = DWDStationRequest(
    station_ids=[1048,4411],
    parameter=[Parameter.CLIMATE_SUMMARY, Parameter.SOLAR],
    time_resolution=TimeResolution.DAILY,
    start_date="1990-01-01",
    end_date="2020-01-01",
    tidy_data=True,
    humanize_column_names=True,
    write_file=True,
    prefer_local=True
)

for df in request.collect_data():
    # analyse the station here

Get data for specific stations from the command line:

# Get list of all stations for daily climate summary data in JSON format
wetterdienst stations --parameter=kl --resolution=daily --period=recent

# Get daily climate summary data for specific stations
wetterdienst readings --station=1048,4411 --parameter=kl --resolution=daily --period=recent

Documentation

We strongly recommend reading the full documentation, which will be updated continuously as we make progress with this library:
