Description:

The mountain Acid Deposition Program (MADPro) was initiated in 1993 as part of the research necessary to support the objectives of the Clean Air Status and Trends Network (CASTNet), which was created to address the requirements of the Clean Air Act Amendments (CAAA). The two main objectives of MADPro were to develop cloudwater measurement systems to be used in a network monitoring environment and to update the cloudwater concentration and deposition data collected in the Applachian Mountains during the National Acid Precipitation Assessment Program (NAPAP) in at three permanent mountaintop sampling stations. These sampling stations were located at Whiteface Mountain, New York; Clingman's Dome, Tennessee; and Whitetop Mountain, Virginia. A mobile manual sampling station was also operated at two locations in the Catskill Mountains in New York during 1995, 1997, and 1998.

Concentration ranges for the ions reported for MADPro are comparable to concentration ranges reported for the Canadian High Elevation Fog (CHEF) project and the Mountain Cloud Chemistry Program (MCCP). However, the MADPro means are higher for all four major ions for Whiteface and Whitetop Mountains in comparison to MCCP results. In general, the MADPro mean calculated deposition values (CLOUD model) for water and four major ions, when compared to MCCP values and several other studies, fall within the range of those measured previously for Clingman's Dome and Whitetop Mountain, while those from the MADPro Whiteface Mountain site are slightly above the range.
