Welcome to the National Weather Service (NWS) Automated
Surface Observing System (ASOS) Change Management Home Page. This page
provides information on pending ASOS changes and the change control
process, as well as sensor photographs linked to sensor information.
Links to other ASOS pages, including State maps depicting ASOS locations,
are also provided.
The NWS Change Management Section administers the configuration/change
control process for ASOS. ASOS Requests for Change (RC) are submitted
by participating agencies, which include the NWS, the Federal Aviation
Administration, and the Department of Defense (Navy and Air Force). Technical,
engineering, and meteorological aspects of RCs are evaluated by the ASOS
Configuration Control Board (ACCB). Through these evaluations, the ACCB
determines whether the RC should be forwarded to the higher-level ASOS
Program Management Committee (APMC) for adjudication. The ACCB also determines
test strategies, working group activities, and implementation priorities.
The higher-level APMC is tasked with providing management oversight for
program issues and major change control.
