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.本数据集涵盖密西西比河流域内5个监测站点共200年的年平均、最低与最高径流量数据，监测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）。 该数据集可用于检验三类径流量指标的增长趋势，亦可用于探究其与北大西洋涛动（North Atlantic Oscillation, NAO）指数所表征的气压差之间的相关性。 本数据集还可通过建模或结合其他数据集开展综合评估，为气候变化评估相关研究提供支撑。
