KNMI-py

Python wrapper to fetch and parse observations from KNMI, either as csv or Pandas DataFrame

See http://knmi.nl/kennis-en-datacentrum/achtergrond/data-ophalen-vanuit-een-script

Note: This library is not affiliated in any way with KNMI, it only uses the KNMI API to request data.

Currently only daily data is implemented.

Installation

KNMI-py is available via pip.

python -m pip install knmi-py

5 Functions

knmi.get_day_data_raw(stations, start, end, inseason, variables)
knmi.get_day_data_dataframe(stations, start, end, inseason, variables)
knmi.get_hour_data_raw(stations, start, end, inseason, variables)
knmi.get_hour_data_dataframe(stations, start, end, inseason, variables)
knmi.get_forecast_dataframe(station, conform_values, variables)

Metadata

Don't know which station number you need, or what the variables mean? We got you covered:

knmi.stations provides a list of all available stations
knmi.variables provides a list of all variables and explanations

Metadata included in DataFrame

All raw data is included as argument to the DataFrame (however, the data is lost once you start manipulating the frame, so you'll have to copy it)

Example

import knmi
df = knmi.get_day_data_dataframe(stations=[260])
print(df.disclaimer)
print(df.stations)
print(df.legend)
df = df.rename(columns=df.legend)
print(df)
