For this project, a series of climate simulations will be performed over the Northern Great Plains during the 1990s deluge period which will characterize wetlands for integration into a regional climate model environment. The characterization of wetlands will be accomplished by merging two disparate data sources: the National Wetlands Inventory compiled by the United States Fish and Wildlife service, and remotely-derived information on surface water coverage derived by the National Climatic Data Center. The series of 4-5 short, 10-day-to-one-month simulations will focus on significant rainfall periods at a range of model resolutions in the range of 10-80 km or lower over the Great Plains. These activities represent a first step in testing the hypothesis that wetland-dominated continental regions influence local and regional climates. This project has ramifications for climate change issues and is therefore expected to serve the climate science community and the general public. Limited educational impact arising from the work is anticipated.

对于该项目，将在 20 世纪 90 年代的洪水时期对北部大平原进行一系列气候模拟，模拟湿地的特征，以便将其纳入区域气候模型环境。 湿地的特征描述将通过合并两个不同的数据源来完成：美国鱼类和野生动物局编制的国家湿地清单，以及国家气候数据中心获得的地表水覆盖范围的远程信息。 这一系列为期 4-5 个为期 10 天到一个月的短期模拟将重点关注大平原上 10-80 公里或更低范围内一系列模型分辨率的显着降雨期。 这些活动代表了检验湿地主导的大陆地区影响当地和区域气候这一假设的第一步。 该项目对气候变化问题产生影响，因此预计将为气候科学界和公众提供服务。 预计这项工作产生的教育影响有限。
