DMI Open Data API

Simple Python interface to the The Danish Meteorological Institute's (DMI) v2 Open Data API.

Weather data from Denmark and Greenland are publicly available through DMI's Open Data API. Fetch raw weather observations from all available weather stations in Denmark and Greenland. Parameters available include temperature, windspeed, humidity, pressure, _precipitation__, and many more.

Requirements

Python 3.6+
API Key for metObs v2 from DMI Open Data
(Optional) API Key for climateData v2 from DMI Open Data

Installation

$ pip install dmi-open-data

Example

from datetime import datetime
import os

from dmi_open_data import DMIOpenDataClient, Parameter, ClimateDataParameter


# Get 10 stations
client = DMIOpenDataClient(api_key=os.getenv('DMI_API_KEY'))
stations = client.get_stations(limit=10)

# Get all stations
stations = client.get_stations()

# Get DMI station
dmi_station = next(
    station
    for station in stations
    if station['properties']['name'].lower() == 'dmi')

# Get closest station
closest_station = client.get_closest_station(
    latitude=55.707722,
    longitude=12.562119)

# Get available parameters
parameters = client.list_parameters()

# Get temperature observations from DMI station in given time period
observations = client.get_observations(
    parameter=Parameter.TempDry,
    station_id=dmi_station['properties']['stationId'],
    from_time=datetime(2021, 7, 20),
    to_time=datetime(2021, 7, 24),
    limit=1000)

# Init climate data client
climate_data_client = DMIOpenDataClient(api_key=os.getenv('DMI_CLIMATE_DATA_API_KEY'))

# Get climate data
climate_data = climate_data_client.get_climate_data(
    parameter=ClimateDataParameter.MeanTemp,
    station_id=dmi_station['properties']['stationId'],
    from_time=datetime(2021, 7, 20),
    to_time=datetime(2021, 7, 24),
    time_resolution='day',
    limit=1000)

API Key

API Key can be obtained for free at the DMI Open Data.
