U.S. Controlled Time Series Radiosonde Observations, daily from 1948

U.S. controlled station time series of upper air observations (soundings) comprise the data in this set. From the National Climatic Data Center (NCDC), DSS obtains annual updates of the DSI 6301 UPPER AIR DIGITAL FILES, which are then quality checked, reformatted, hydrostatically checked, and merged into existing station time series.

Primarily, stations are located in the contiguous U.S., Alaska, the Caribbean, Hawaii and other Pacific Islands, plus Keflavik, Ascension Island, Diego Garcia, and the South Pole. There are currently about 110 stations received.

Mandatory, standard, and significant levels may include pressure, height, temperature, moisture, wind direction and speed. Earliest data is for 1945, but periods of record vary widely among the stations.

本数据集包含由美国控制站收集的平流层观测（探空）时间序列数据。国家气候数据中心（NCDC）向DSS提供DSI 6301平流层数字文件年度更新，随后对这些文件进行质量控制、格式转换、静力检查，并将其合并至现有站时间序列中。主要而言，站点分布在美国本土、阿拉斯加、加勒比地区、夏威夷及其他太平洋岛屿，以及凯夫拉维克、阿森松岛、迭戈加西亚和南极洲。目前约有110个站点数据接收。强制性的、标准的和重要的观测水平可能包括气压、高度、温度、湿度、风向和风速。最早的数据可追溯至1945年，但各站记录时期存在较大差异。
