这份文件描述了一个数据库，其中包含毗邻的美国1221个站的月度温度和降水量数据。这个被称为美国历史气候学网络(US HCN)的观测站网络和由此产生的数据库是由北卡罗来纳州阿什维尔的国家气候数据中心汇编的。这些数据代表了美国在区域范围内分析长期气候趋势所能获得的最佳数据。大多数台站的数据持续到1994年12月31日，大多数台站记录至少连续完成了80年。与过去气候研究中使用的许多数据集不同，这些数据进行了调整，以消除因站点移动、仪器变化、观测时间差异和城市化影响而产生的偏差。这些月度数据可以从二氧化碳信息分析中心以数字数据包(NDP)的形式免费获得。NDP包括本文件和27个机器可读数据文件，其中包括支持数据文件、描述性文件和计算机访问代码。本文档描述了如何选择美国HCN中的站点以及如何处理数据，定义了数据的限制和限制，描述了磁性介质的格式和内容，并提供了讨论在US HCN中使用的编辑和调整技术的文献的重印本。
This document describes a database containing monthly temperature and precipitation data for 1221 stations in the contiguous United States. This network of stations, known as the United States Historical Climatology Network (US HCN), and the resulting database were compiled by the National Climatic Data Center, Asheville, North Carolina. These data represent the best available data from the United States for analyzing long-term climate trends on a regional scale. The data for most stations extend through December 31, 1994, and a majority of the station records are serially complete for at least 80 years. Unlike many data sets that have been used in past climate studies, these data have been adjusted to remove biases introduced by station moves, instrument changes, time-of-observation differences, and urbanization effects. These monthly data are available free of charge as a numeric data package (NDP) from the Carbon Dioxide Information Analysis Center. The NDP includes this document and 27 machine-readable data files consisting of supporting data files, a descriptive file, and computer access codes. This document describes how the stations in the US HCN were selected and how the data were processed, defines limitations and restrictions of the data, describes the format and contents of the magnetic media, and provides reprints of literature that discuss the editing and adjustment techniques used in the US HCN.
