The input of inorganic ions to spruce forests by dry deposition of aerosol particles

In order to estimate the dry deposition of the major inorganic ions to two different spruce standsthe input parameters of a model for determining the deposition velocity were continuously measured. Size specific samples of particulate matter were collected at the same sites with five-stage Berner impactors. The dry deposition flux F was calculated by multiplying these concentrations by the deposition velocity specific to each measuring interval and size class.
