ASOS 1 Minute Surface Data

ASOS 1 Minute Surface Data is digital data set DSI-3285, archived at the National Climatic Data Center (NCDC). This is meteorological data. This is a new data set using data from the Automated Surface Observations System (ASOS), and is expected to replace autographic charts. The data is expected to have the same uses, including quality control of lower resolution data, climatological research, litigation, insurance investigations, hydrological research, and engineering design. The stations are operated by the National Weather Service (NWS) and the Federal Aviation Administration (FAA). They are located in the US, Puerto Rico, Guam, American Samoa and the Pacific Ocean nations of Marshall Islands, Micronesia, and Palau. ASOS collects data continuously. Parameters are shown in the list below. One- minute reports (30-second reports for cloud data) are computed from data accumulations over the time periods shown prior to the report: Cloud Height 30 seconds Cloud Layer Thickness 30 seconds Visibility 1 minute Present Weather 10 minutes Freezing Rain 15 minutes Temperature/Dew Point 1 minute Wind 2 minutes Pressure 1 minute Precipitation Accumulation 1 minute.
