The National Morbidity, Mortality, and Air Pollution Study (NMMAPS) was a large national study of air pollution and health in the United States. The study examined 108 cities spanning the years from 1987 to 2000. However initially it was available at Health and Air Pollution Surveillance System (iHAPSS), after 2011 it was removed from the site.
Could you advise where from can the NMMAPS data be obtained?
