Subject:   Upgrade to Global (multi_1) Wave Model Point Data

           Effective January 12, 2016


Effective January 12, 2016, beginning with the 1200 Coordinated

Universal Time (UTC) run, the National Centers for Environmental

Prediction (NCEP) will upgrade the Global Wave Model to update

existing buoy points and add new ones.


Data Point Additions:


The point output data going to NOAAPORT from the multi_1 model

are being expanded to include new points. For the detailed list

of the coordinates, station names and corresponding WMO headers

view Table 1 here:


Data Point Changes:


The output point coordinates for a select set of stations were

changed to better specify the boundary for the local wave model

in the Philadelphia region. See Table 2 for the original and new

coordinates in the same link above.


Sample data feed is available here:


On implementation day, the data will be disseminated across

NOAAPORT with the WMO headers as described.
