History of Acid Precipitation on the Shawangunk Ridge: Mohonk Preserve Precipitation Depths and pH, 1976 to Present

We, the staff, volunteers and associates of the Mohonk Preserve, have been collecting precipitation data at Mohonk Lake since January 1976. The Level1_MohonkPrecipData includes precipitation depths recorded either during or at the conclusion of every precipitation event. This dataset additionally includes pH measurements for most precipitation collections.The Level2_MohonkPrecipData summarizes data collections into precipitation events where the precipitation depth is cumulative and the pH is averaged for all data collections in that event. We measured precipitation via a National Weather Service Rain Gauge and the pH was measured at a Cooperative Weather Service Station at Mohonk Lake.
