The Air Quality Monitoring Team (AQMT) at UC Davis has operated the Interagency Monitoring of Protected Visual Environments (IMPROVE) ambient speciated particulate monitoring network since its inception in 1988. Beginning in 2015, AQMT took on the laboratory analysis and data handling for the Chemical Speciation Network (CSN). These two networks encompass over 300 sites delivering over 60 PM2.5 species across the country every third day.
IMPROVE sites are located in beautiful Class I areas: visibility protected national parks and national wilderness areas larger than 6,000 acres and 5,000 acres—respectively—and include lands managed by Native American Tribes, U.S. Fish and Wildlife Service, U.S. Forest Service, and the National Park Service. The IMPROVE calendars showcase these Class I areas with stunning images captured by AQRC/IMPROVE staff on location.
