1-Minute Page 2 Surface Weather Observations from the Automated Surface Observing Systems (ASOS) Network

browse graphicASOS weather sensors (credit: NOAA/NWS)
This dataset includes one-minute observations for precipitation type and amount, station pressure, temperature, dew point temperature, lightning detection elements, and the Frozen Precipitation Sensor Frequency for approximately 900 stations in the U.S., Puerto Rico, the U.S. Virgin Islands, and some Pacific island territories as part of the Automated Surface Observing Systems (ASOS) network. The ASOS Program is a joint effort of the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the Department of Defense (DOD). The ASOS network was designed to support weather forecast activities and aviation operations and, at the same time, support the needs of the meteorological, hydrological, and climatological research communities. The ASOS 1-minute page 1 and page 2 data were collected and processed by the NOAA National Centers for Environmental Information (NCEI).

Lineage information for: dataset
Lineage StatementThe data have been archived by the NOAA National Centers for Environmental Information.
Processing Steps
  • The NOAA National Centers for Environmental Information acquired and processed the station data from the ASOS network within one day of the observations. The data processing steps included data acquisition, basic quality assurance, assimilation into monthly station files, and data archive and access. The basic quality assurance included identifying improper record formats, incorrectly transmitted station IDs, and determining if record lengths and observing dates and times are within acceptable bounds. Additional data for the previous month may have been processed and made available during the first to third day of the following month, and on rare occasions later in that month, due to technical issues that delayed the processing of data in real-time.
