AIRMoN Purpose
Whereas the NTN was designed to characterize long-term trends in the chemical climate of the U.S., AIRMoN was designed to provide data with a greater temporal resolution. This short-term resolution is critical for:
  • Determining the effectiveness of emission controls mandated by the Clean Air Act;
  • Evaluating the potential impacts of new sources of emissions on protected areas such as Class I Wilderness Areas; and
  • Identifying source/receptor relationships in atmospheric models.

Currently, the AIRMoN network comprises seven sites where precipitation samples are collected daily or on an event basis. Data are available from some sites since October 1992.

Additional information about the AIRMoN program, as well as a full discussion of the AIRMoN-wet and AIRMoN-dry components of the program, can be found on NOAA's AIRMoN Web Page.
