National Weather Service; Automated Surface Observing System

The National Weather Service (NWS) implemented the Supplemental Data Program effective October 1, 1995. This program supplements data provided by the Automated Surface Observing System (ASOS). Observations produced through the Supplementary Data Program are transmitted separately from the ASOS operations and provide data to support hydrometeorological operations and climatological applications. This notice explains the reasons for the shift in reporting methods and describes how to obtain and interpret hydrometeorological information that was previously available in the surface aviation observation (SAO) format.
