Atmospheric precipitation chemistry data
Measurements of atmospheric precipitation chemistry help us monitor and understand air quality. Precipitation chemistry is the measure of different pollutants in rain and snow. The collectors open only during these rain and snow events. Measurements are from instruments located at the earth’s surface (ground-based).
The NAtChem archive contains the following data:
Data from measurements of precipitation chemistry are available as early as 1976.
You can also get data files from all of the measurements of precipitation chemistry
Information about how and where air quality data are measured is available from this link:
Data from urban sites are archived and distributed separately by the National Air Pollution Surveillance Program (NAPS).
Further reading on how we measure and produce these data is in the documentation below.
