PM10 is particulate matter, which is very small, remains suspended in the air for periods of time, and is easily inhaled into the deep lung. Increased death and disease have been linked to periods of high outdoor PM10 concentrations. An annual arithmetic average of PM10 should not exceed 50 ug/m3.</abstract><purpose>This dataset is used as an example of environmental data for geostatistical spatial data analysis using Geostatistical Analyst extension in ArcGIS 8.</purpose><supplinf>The data were extracted from the California Air Resources Board's ambient air quality databases CD. The data was projected to the NAD83 US Albers coordinate system used by the rest of the data for this project.</supplinf></descript><citation><citeinfo><origin>Air Resources Board, California Environmental Protection Agency</origin><pubdate>20001101</pubdate><title>Annual geometric mean particulate matter with a mass median aerodynamic diameter less than 10 micrometers in micrograms per cubic meter of air (ug/m3)</title><ftname Sync="TRUE">ca_pm10_pts</ftname><geoform Sync="TRUE">vector digital data</geoform><edition>2000</edition><serinfo><sername>ESRI Data &amp; Maps</sername><issue>2000</issue></serinfo><pubinfo><pubplace>Redlands, California, USA</pubplace><publish>Environmental Systems Research Institute, Inc.
