NWEM data elements are added during the reformatting that occurs at the HazCollect server. Although these elements are also derived, we have classified them in a category of their own.
The descriptions of the NWS supplied values are provided primarily for an understanding of the source and meaning of the remaining items, all of which are displayed in the final NWEM.
NWS Supplied Values
WMO Heading
The WMO Heading is included for routing purposes. (For further details), see the Net Links below.
- AWIPS ID
The first three characters of the AWIPS ID are derived from the NWEM type, previously mentioned in Lesson 3.3. The second three characters identify the cognizant Weather Field Office.
- Universal Geographic Code (UGC)
The first six characters of the UGC include a two letter state code, the letter C designating the county form of UGC, and a three number county code derived from a Federal Information Processing Standards (FIPS) code, passed to the HazCollect server by the authoring software. The "$$" symbol delimits the portion of the message to which the UGC applies.
- Broadcast Instruction
The identical broadcast instruction is added for all NWEMs transmitted through HazCollect:
BULLETIN - EAS ACTIVATION REQUESTED
- NWS Relaying Office
The NWS Relaying Office is derived based on county location and identified in an added statement:
RELAYED BY NATIONAL WEATHER SERVICE [CityName StateCode]
- Relay Text
The requesting COG is derived from a HazCollect record created during the authorization process and identified in an added statement:
