Abstract |
In the International Sulfur Deposition Model Evaluation seasonal and annual wet sulfur deposition amounts over eastern North America predicted by twelve models will be statistically compared with deposition amounts derived from networks in the same region. Since the methods for quality control and quality assurance of the precipitation chemistry data and procedure for computing wet deposition amounts are not always in agreement between the networks, it was necessary to adopt unified procedures for screening/correcting the data and computing deposition amounts. A scheme was also developed for estimating the uncertainties in the wet deposition amounts. The procedures for computing wet deposition amounts and estimating the associated uncertainties are described and results from five networks in eastern North America are given. |
