This report describes the preparation of a third series of reference materials for the chemical analysis of natural precipitation samples. They will be used as a means of intercalibrating atmospheric monitoring stations. These materials consist of high and low concentrates which upon dilution simulate the range of anion and cation concentrations typically found in natural rainwater. Two separate reference samples which are to be used undiluted are provided for evaluation of acidity measurements.
