Daily Meteorological Data for U.S. Cooperative Stations from NCDC TD3200

The summaries of daily land surface observations in this data set are primarily from stations in the National Weather Service (NWS) cooperative station network, but also include NWS principal (first order) climatological stations, and stations supported by the Federal Aviation Administration (FAA), National Park Service (NPS), Bureau of Land Management (BLM), U.S. Forest Service (USFC), U.S. Geological Survey (USGS), and Tennessee Valley Authority (TVA), along with a handful of stations at Air Force and Navy bases. The sites are located in the contiguous U.S., Alaska, Puerto Rico, Virgin Islands, Hawaii and other Pacific Islands.

The major parameters are daily weather, precipitation, snowfall, snow depth, maximum temperature, minimum temperature, and observation temperature. The earliest data is for 1854, but most stations begin in 1948. Periods of record vary widely among the stations.

本数据集中每日陆地表面观测的概要主要来自国家气象服务（NWS）合作站网，亦包含NWS一级（首要）气候站，以及由联邦航空管理局（FAA）、国家公园管理局（NPS）、土地管理局（BLM）、美国森林服务局（USFC）、美国地质调查局（USGS）和田纳西河谷管理局（TVA）支持的站点，此外还包括少量位于空军和海军基地的站点。这些站点遍布美国本土、阿拉斯加、波多黎各、维尔京群岛、夏威夷及其他太平洋岛屿。
主要参数包括每日天气、降水量、降雪量、积雪深度、最高温度、最低温度和观测温度。最早的数据可追溯至1854年，但大多数站点的数据始于1948年。各站点的记录时期差异较大。
