Weather Service Modernization Criteria

In accordance with the Weather Service Modernization Act, 15 U.S.C. 313n. (the Act), the National Weather Service (NWS) is publishing an amendment to its criteria for modernization actions requiring certification. This amendment adds criteria unique to automating a field office at service level D airports to ensure that automation actions will not result in any degradation of service. Automating a field office occurs after automated surface observing system (ASOS) equipment is installed and commissioned at a field office and the NWS employees that were performing surface observations at that office are removed or reassigned.
