Applications of Within-Event Precipitation Chemistry Measurements

Source

Chemical measurements from hourly sequential precipitation samples and simultaneous meteorological measurements and observations were analyzed to discover relationships between chemical species, infer atmospheric mechanisms, relate precipitation chemistry to meteorological events and conditions, and identify probable pollutant source regions. Analytical methods that can be applied to short-period samples, but usually not to event, weekly, or monthly samples, are described and illustrated.

Changes in concentrations of chemical species during precipitation events can be documented and used to infer atmospheric processes. These changes can be related also to meteorological conditions such as changes in rainfall rate and wind direction or to frontal passages. Source directions and probable source regions can be located by wind direction and trajectory analyses. Means of many samples taken under similar conditions can document relationships between meteorological conditions, concentrations in precipitation, and amounts of wet deposition.
