Project Title & Description
Iowa Ambient Air Monitoring Network 2011
The Iowa Department of Natural Resources operates and maintains an ambient air monitoring network for compliance with the fine particulate matter National Ambient Air Quality Standard as set forth in the Clean Air Act. The fine particulate matter standard (PM2.5) was promulgated in 1997 and is small particulate matter 2.5 micrometers in diameter or smaller. Fine particulates are linked with a number of serious health issues and are also a visibility impairment. The monitoring network is necessary to measure levels of PM2.5 in the atmosphere. Data from the monitors is used to provide information to the public on levels of particulate matter pollution in Iowa communities, and assists to examine particle pollution trends throughout the country.
