Abstract

A method to obtain estimates of the volume of fogwater collected by a tree canopy in complex terrain is described. Included are assumptions about the shape and spacing of the trees and their fogwater collection efficiency. A key component is the use of a computer model for wind flow in complex terrain. The fogwater volume results enable a mapping of wet deposition patterns of acidic ions. Fog chemistry data from the Roundtop Mountain complex in southern Quebec are used for calibration purposes. 1 Introduction To evaluate the impact of cloudwater chemistry on high-elevation forests in the Chemistry of High Elevation Fog (CHEF) project, Schernenauer* suggested that estimates of the spatial distribution of
