Abstract
A 6-month field intercomparison study on precipitation measurements was performed at Schagerbrug near the west coast in the Netherlands. Twenty bulk sampling systems and two wet-only samplers were evaluated on accuracy, sampling strategy and performance under field conditions. Bulk precipitation fluxes of NO 3 −, NH 4 +, H + and Kjeldahl-N generally could be determined with a greater accuracy than bulk precipitation fluxes of SO 4 2−, Na +, Cl −, Mg 2+, Ca 2+, Alkalinity and H +. Bulk precipitation fluxes of K + generally had the lowest accuracy. Only 20% of the sampling systems differed less than 10% from the best estimate, whereas most systems (60%) differed more than 20% from the best estimate. The inaccuracy induced by the sampling system appeared to be much larger than that resulting from the analysis of the samples by different laboratories as determined by ring-tests.
