Atmospheric deposition to remote receptors I. Precipitation quantities from the Ilwas-network

Abstract

A dense precipitation network was operated for 45 mo in three remote watersheds in the Adirondack Park of New York State. The network consisted of 4 to 7 wet/dry collectors spaced 3 m to 30 km apart; network operation was on an event basis. The chief objective was an accurate determination of atmospheric inputs into the three watersheds and an assessment of intra- and interbasin variability. Approximately 96% of all possible events were captured. One of the watersheds, Sagamore, received from 6 to 36% less precipitation on a seasonal basis. The capture efficiency relationship between volume collected and standard rain gauge was quantified and shown to be a function of precipitation quantity, type, and sampler location.
