Automated Surface Observing System (ASOS)
ASOS serves as a primary climatological observing network in the United States. Not every ASOS is located at an airport; for example, one of these units is located at Central Park in New York City. ASOS data are archived in the Global Surface Hourly database, with data from as early as 1901.
