This dataset includes one-minute observations for visibility extinction coefficient, 2-minute average and 5-second peak wind speed and direction, and runway visual range 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).
