Subject: Change to the delivery time of Extratropical Surge and

         Tide Operational Forecast System for the Atlantic and

         Gulf coasts (ESTOFS Atlantic) effective January 7, 2014.

         ESTOFS Atlantic will be provided over SBN and NOAAPORT

         effective February 18, 2014

 

Effective January 7, 2014, beginning with the 1200 Coordinated

Universal Time (UTC) model cycle, the Extratropical Surge and

Tide Operational Forecast System for the Atlantic and Gulf coasts

(ESTOFS Atlantic) model output will be delivered 20 minutes

earlier than the current delivery time. This change in delivery

time is a result of optimization of the model code. 

 

Effective February 18, 2014, beginning with the 1200 Coordinated

Universal Time (UTC) cycle, ESTOFS Atlantic will be added to the

Satellite Broadcast Network (SBN)and NOAAPORT. These grids will

be disseminated in GRIB2 format.

 

For technical details about ESTOFS please see: Technical

Information Notice (TIN) 12-43:

 

http://www.nws.noaa.gov/om/notification/tin12-43estofs.htm

 

ESTOFS output will be reprojected from the ADvanced CIRCulation

(ADCIRC) native finite element grid to the 2.5 km National

Digital Forecast Database (NDFD) Continental United States grid

and the 1.25 km NDFD Puerto Rico grid. 

 

GRIB2 files will be created for each hourly prediction

(astronomical tides), and sub-tidal water levels (the isolated

surge). GRIB2 files will be available 6.5 hours after the

synoptic time (OO, 06, 12, 18 UTC.) The per cycle data volume

will be approximately 500 MB.

 

The WMO Headings for these products will be as follows: 

 

   T1:     Data Format of GRIB2 - E

   T2:     Parameter code - C, E, or H

   A1:     Grid code - P for Puerto Rico or I for CONUS 

   A2:     Forecast time interval- one of

           ABCDEFGHIJKLMNOPQRSTUVWXYZ

   II:     Layer or level: 88

   CCCC:   KWBM
