Interactive Map
Select which layers to display on the map, zoom in, find monitor locations, and download data from popup balloons. The monitoring site information is also available in spreadsheet format. For more information regarding the map layers, read the Air Quality KML Files documentation (PDF, 165 KB). In 2009, lead began being measured and reported in TSP (Total Suspended Particulates) and PM10 in "Local Conditions" (LC). Layers for those parameters are provided on this page. For more information regarding lead, see this technical note on lead data reporting.
