Automated Weather Observing System (AWOS)

Automated Weather Observing System (AWOS) units are operated and controlled by the Federal Aviation Administration. These systems are among the oldest automated weather stations and predate ASOS. They generally report at 20-minute intervals and do not report special observations for rapidly changing weather conditions.

AWOS data are archived in the Global Surface Hourly database, with data from as early as 1901.
