This report describes the preparation of a series of reference materials for chemical analysis of natural precipitation. This is the second series of such materials prepared by NBS, under the sponsorship of EPA, and will be distributed by the latter as a means to intercalibrate atmospheric monitoring stations. The materials consist of ampoules of concentrates which can be diluted to simulate natural rainwater. A separate reference sample, to be used undiluted, is provided for evaluation acidity measurements. The analytical measurements made to establish the composition of the samples are also described.
