niluclient

Python client for getting air pollution data from NILU sensor stations in Norway. The package comes with clients that can fetch and cache data from nilus api.

Acknowledgements

According to the api documentation from nilu.no and luftkvalitet.info, when using data fetched through this client an acknowledgement to both nilu.no and luftkvalitet.info needs to be included.

Usage

Finding all station in an area:

import niluclient as nilu

stations = nilu.lookup_stations_in_area('Bergen')

Finding all stations and sensor reading within 20 km from a location:

import niluclient as nilu

client = nilu.create_location_client(60.123456, 5.123456)

# name of all stations found.
station_names = client.station_names

# dict of all stations with readings.
stations = client.station_data

# all stations NO2 readings
for station in stations:
    no2_value = station.sensors[nilu.NO2].value

Finding readings from a specified station, and update cached value:

import niluclient as nilu

client = nilu.create_station_client('Kannik')
no2_value = client.data.sensors[nilu.NO2].value
no2_unit = client.data.sensors[nilu.NO2].unit_of_measurement

# after an hour. (Data from the api will only update on the hour) 
client.update()

new_no2_value = client.data.sensors[nilu.NO2].value
