Explanation of the wind rose diagram

Wind rose diagram - Stockton

The map above shows hourly average data for all parameters, i.e., PM10, PM2.5, NO2, SO2, NH3, wind speed and wind direction values. All readings are updated hourly. Note that the map shows hourly averages for PM10 and PM2.5, and not rolling 24-hour averages as was the case prior to February 2020.

The hourly values for pollutants are categorised into the following air quality ratings:
