Data Disclaimer

The data presented here represent measurements of the concentrations of fine particulate matter in the ambient air that have been sampled continuously (except for internal machine checks) and then reported at the end of each hour. The data here are not final, and some modification of the data may subsequently occur as a result of quality assurance review. In particular, a disruption in normal analyzer operation may appear as a large spike on the graph, and as a value exceeding 800 in the table. These points are removed in the quality reviews. Representations of health risk are provided as general advisories, and are not substitutes for individual health awareness and the advice of medical professionals.
