Continuous air quality monitoring network (LUQS, current air quality)

LUQS, the air quality monitoring system of the state of North Rhine-Westphalia, records and investigates the concentrations of various pollutants in the air. The measuring system integrates continuous and discontinuous measurements and provides a comprehensive representation of the air quality data. The data offered here are continuously measured and updated hourly measured values of the last 24 hours of different components (fine dust PM10, sulphur dioxide, nitrogen dioxide, nitric oxide, ozone, relative humidity, temperature, wind speed, wind direction) from all stations. All the metrics you see here are preliminary! They are not yet validated! This applies in particular to PM10 data. The time is specified in CET and corresponds to the winter time valid in NRW (NRW-summer time = CET + 1 hour).
