Acidic wet deposition (acid rain) is thought to be responsible for a variety of deleterious effects on ecosystems and on natural and man-made materials. Determining and quantitating these effects is complicated by the fact that rain is a low ionic strength solution of many different salts and organic compounds. The report describes the features and performance of a monitor that was designed to fractionate a rain event into samples corresponding to 0.3 mm of rain, determine the pH and conductivity of the sample within approximately one minute of collection, and store the remainder of the sample for more detailed analysis.
