Continuous Air Quality Monitoring Network (LUQS, Current Air Quality)

LUQS, the air quality monitoring system of the state of North Rhine-Westphalia, records and examines the concentrations of various pollutants in the air. The measurement system integrates continuous and discontinuous measurements and provides a comprehensive representation of air quality data. The data offered here are continuously measured and hourly updated readings of the last 24 hours of various components (particulate matter PM10, sulfur dioxide, nitrogen dioxide, nitrogen monoxide, ozone, relative humidity, temperature, wind speed, wind direction) from all stations. All readings you see here are preliminary! They have not yet been finally validated! This is especially true for PM10 data. The time is given in CET and corresponds to the winter time valid in NRW (NRW summer time = CET + 1 hour).
