The University of Michigan Air Quality Laboratory participates in a number of varied research programs, many of which rely on the dedicated efforts of public citizens who operate a number of our air quality monitoring stations. Without thes efforts of these individuals, our work would be considerably more difficult to perform. In an effort to allow these individuals, as well as others, to see the fruits of their efforts, the University of Michigan Air Quality Laboratory publishes a series of newsletters which summarizes our "to-date" results of our numerous research programs. The most recent UMAQL Newsletters can be found below:
