Title
WEATHER MESSAGE SWITCHING CENTER REPLACEMENT SYSTEM SPECIFICATION

Federal Aviation Administration

Publication Date:
Jul 25, 1990

Scope:

Purpose. The WMSCR's primary purpose is to collect and process weather data for distribution to users within the NAS. In addition, the WMSCR will collect Notices to Airmen (NOTAM) from the FSS environment for processing by the Consolidated NOTAM System Processor (CNSP) and will store and distribute the processed NOTAMs received from the CNSP. It will collect, process, and distribute weather data, along with storing and distributing NOTAMs, for users of aviation weather products. The WMSCR will replace the current Weather Message Switching Center (WMSC) system in Kansas City, Missouri. It will support all functions related to weather processing presently performed by the WMSC, plus storage and distribution of NOTAMs. In addition, it will have a graphic data distribution capability. The WMSCR will consist of two identical nodes located at the National Aviation Weather Processing Facility (NAWPF) sites in Salt Lake City, Utah and in Atlanta, Georgia; that will provide geographical redundancy and increase operational availability. Each WMSCR node will normally serve approximately half the system. If one node fails, the surviving node will assume complete system operation. Figure 1. WMSCR System Interconnection Diagram
