This dataset includes five-minute reports with elements for wind speed and direction, visibility, present weather, temperature, dew point temperature, station altimeter, pressure and density altitude, and relative humidity 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 5-minute data were collected and processed by the NOAA National Centers for Environmental Information (NCEI).
