![]() Professional researchers wishing to use this data are encouraged to contact Berkeley Earth to discuss these issues further. Be aware that changes in the station network may have introduced biases in these results. In addition, the number of stations available and their spatial distribution is likely to change over time. Automated quality control processes are used to identify erroneous data, but additional corrections may be necessary. Since real-time data is used, these time series should be regarded as preliminary and subject to change. As the intent is to capture regional variations in air quality, be aware that individual air quality monitors may report somewhat higher or lower values for PM 2.5 concentrations than the values represented by the local averages reported here. These data are based on the regional interpolation of real-time observations by ground-level monitoring stations. Hourly concentration observations are provided for this location in a simple text format.
