Description: Particulate Matter (PM) pollution data are reported to the Environmental Protection Agency and stored in AQS (the Air Quality System data mart). Representative particulate matter monitors are within 10 km of park boundaries. In-park or nearby representative monitoring sites can measure both PM2.5 and PM10 but there are sites that only measure PM2.5 or PM10. In those cases where both PM2.5 and PM10 are not available from one site, parks may have two representative particulate matter monitors where one represents PM2.5 and the other PM10. Note that sometimes supplementary representative monitoring sites monitors both PM2.5 and PM10 but only the missing PM is used from that monitor. If there is not a nearby representative site that could supplement the missing data, the park will only have PM2.5 or PM10. FRM or FEM monitors take precedence over in-park or nearby representative IMPROVE monitors. This is because IMPROVE data are collected only every 3 days resulting in less data for condition assessments. There are a handful of representative monitors that are no longer the closest monitor within a 10 km radius but are retained as the representative monitor to maintain consistent historic trend records.
