GCIP/EAOP-99 Surface: Daily Precipitation Composite. Version 1.0

The Daily Precipitation Composite was formed from several data sources (i.e., National Centers for Environmental Prediction daily precipitation, National Weather Service Cooperative Observers daily precipitation data, W.K. Kellogg Biological Station daily precipitation, USDA Agricultural Research Service NAEW daily precipitation data (Coshocton), Tennessee Valley Authority daily precipitation data, and the daily precipitation data extracted from the GCIP LSA-E EAOP-99 Hourly Precipitation Composite). Data from these sources were quality controlled and merged to form this precipitation composite.每日降水合成数据集（Daily Precipitation Composite）由多源数据融合构建而成，其数据源包括：美国国家环境预报中心（National Centers for Environmental Prediction）每日降水数据、美国国家气象局合作观测站每日降水资料、W.K. 凯洛格生物站（W.K. Kellogg Biological Station）每日降水数据、美国农业部（USDA）农业研究服务局NAEW每日降水数据（科肖克顿站）、田纳西河谷管理局（Tennessee Valley Authority）每日降水资料，以及从GCIP LSA-E EAOP-99小时降水合成数据集中提取的每日降水数据。所有上述源数据均经过质量控制与融合处理，最终形成该降水合成数据集。
