Variability in the discharge of the Mississippi River and tributaries from 1817 to 2020

This is a two-hundred-year long dataset of the annual average, minimum, and maximum discharges at five stations draining the Mississippi River watershed: at Clinton, IA, Herman, MO, St. Louis, MO, Louisville, KY, and Vicksburg, MS. The data are useful to test for increases in the three discharge metrics, and correlations with air pressure differentials represented in the North Atlantic Oscillation (NAO) Index. These data may be useful for climate change assessments through modeling or synthetic assessments using other data sets.

本数据集为时长跨度达两百年的水文监测数据集，覆盖密西西比河流域的5个监测站点，包含各站点的年平均、最低及最高河流流量。这5个站点分别为艾奥瓦州克林顿（Clinton, IA）、密苏里州赫尔曼（Herman, MO）、密苏里州圣路易斯（St. Louis, MO）、肯塔基州路易斯维尔（Louisville, KY）以及密西西比州维克斯堡（Vicksburg, MS）。
本数据集可用于检验三类河流流量指标的变化趋势，以及分析其与北大西洋涛动（North Atlantic Oscillation, NAO）指数所表征的气压差的相关性。此外，该数据集还可通过建模或结合其他数据集开展综合评估，为气候变化评估工作提供支撑。
数据采集方法：检索由密西西比河委员会（美国陆军工程兵团）及美国地质调查局发布的档案记录。
