RC4USCoast: A river chemistry dataset for regional ocean model application in the U.S. East, Gulf of Mexico, and West Coasts from 1950-01-01 to 2022-12-31 (NCEI Accession 0260455)

This dataset, River Chemistry for the U.S. Coast (RC4USCoast), consists of historical records of river chemistry and discharge for 140 monitoring sites along the United States East Coast, the Gulf of Mexico, and the West Coast from 1950 to 2022. RC4USCoast is mostly derived from the Water Quality Database of the U.S. Geological Survey (USGS), but also includes river discharge from the USGS’s Surface-Water Monthly Statistics for the Nation and the U.S. Army Corps of Engineers. RC4USCoast provides monthly time series as well as long-term averaged monthly climatological patterns for twenty-one variables including alkalinity and dissolved inorganic carbon concentration. It is mainly intended as a data product for regional ocean biogeochemical models and carbon chemistry studies in the U.S. coastal regions.

本数据集为美国海岸河流化学数据集（River Chemistry for the U.S. Coast，缩写RC4USCoast），涵盖1950年至2022年间美国东海岸、墨西哥湾及西海岸沿线140个监测站点的河流化学与径流历史观测记录。RC4USCoast的数据源主要来自美国地质调查局（U.S. Geological Survey, USGS）水质数据库，同时还纳入了美国地质调查局《全国地表水月度统计报告》以及美国陆军工程兵团的河流径流量数据。该数据集提供21项变量的月度时间序列与长期平均月度气候态特征，涵盖碱度与溶解无机碳浓度等指标，主要作为配套数据产品服务于美国沿海区域的海洋生物地球化学模型研发与碳化学研究。
