Techniques for pollution monitoring in remote sites: III. Near real-time monitoring of cloud water conductivity and pH

  • Mark T. Hemmerlein

A semi-portable flow-through cloud water monitoring system was developed for measurements of cloud water conductivity and pH in remote sites lacking AC line power. This system was tested from May to September on Camels Hump mountain, Vermont. High temporal resolution data from seven cloud events were collected during the 1991 growing season. Mean cloud water conductivity and pH for all events was 467 μmhos cm−1 and 3.2, respectively. The highest conductivity was 997 (μmhos cm−1 recorded on 19 September 1991 and the lowest pH of 2.9 was recorded during several events over the summer. Data from this system may be used to achieve a better understanding of the chemical environment in areas experiencing forest decline.
