ASOS 5-Minute Weather Duration

ASOS 5-Minute Weather Duration (DSI-6403) is digital data set DSI-6403, archived at the National Climatic Data Center (NCDC). ASOS is Automated Surface Observing System, which is used at several hundred National Weather Service (NWS), Federal Aviation Administration (FAA), and US military stations in the United States of America including Alaska and Hawaii, and Puerto Rico. The earliest data is from June, 1998. DSI-6403 contains a record of all weather events for the reporting site. Reporting sites include all ASOS stations across the US. The beginning and ending time of the weather event is also reported. Weather duration data are derived from DSI-6401, ASOS 5-Minute Data. Weather duration data are used as input to create a climatological product known as the Monthly Airways Extract (MAE), DSI-6407, for those sites. Major parameters include the type of weather event and its begin and end times.

ASOS 5分钟气象时长数据集（DSI-6403）是存档于美国国家气候数据中心（National Climatic Data Center，NCDC）的数字数据集。ASOS即自动地面观测系统（Automated Surface Observing System），在美国本土、阿拉斯加、夏威夷及波多黎各的数百个国家气象局（National Weather Service，NWS）、联邦航空管理局（Federal Aviation Administration，FAA）及美军观测站点中投入使用。该数据集的最早数据可追溯至1998年6月。DSI-6403包含各报告观测站点的全部气象事件记录，同时记录各气象事件的发生与结束时间，报告站点覆盖全美所有ASOS站点。气象时长数据源自ASOS 5分钟数据集（DSI-6401），此类数据被用作输入，为对应站点生成名为月度航空气象摘录（Monthly Airways Extract，MAE）的气候产品，对应数据集编号为DSI-6407。该数据集的核心参数包括气象事件类型及其起止时间。
