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.

在这个项目中，将在1990年代洪水期间对北方大平原进行一系列气候模拟，这将描述湿地的特征，以便纳入区域气候模式环境。 将通过合并两个不同的数据来源来确定湿地的特征：美国鱼类和野生动物局汇编的国家湿地清单和国家气候数据中心获得的关于地表水覆盖范围的远程信息。 这一系列4-5个短的、10天到一个月的模拟将侧重于大平原上10-80公里或更低范围内的一系列模型分辨率下的重大降雨期。 这些活动是检验以湿地为主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有影响，因此预计将为气候科学界和公众服务。 预计这项工作产生的教育影响有限。
