Description
Summary:The data set of N and S compound measurements from WATOX-85 has been examined in detail to assess that data quality and suitability for use in addressing the goals of the Western Atlantic Ocean Experiment. Accuracy estimates for particulate SO 4 2− and NO 3 −, SO 2 and HNO 3 have been made on the basis of the investigators' estimates and the results of intercomparisons. Intercomparisons of ground-based particulate SO 4 2− and all filter SO 2 and HNO 3 measurements show them to be consistent with the 20% accuracies quoted by the investigators. Ground-based particulate NO 3 − and aircraft particulate SO 4 2− show inconsistencies such that the accuracies can be no better than 28% and the aircraft particulate NO 3 has an accuracy of no better than 60%.
