Subject: Soliciting Public Comments on the Removal of

NCEP RTOFS Atlantic Forecasting System

through December 15, 2016

The National Centers for Environmental Prediction (NCEP) has been

running an North Atlantic Basin Real Time Ocean Forecasting System

(RTOFS Atlantic) since December 2005. This system has been superseded

by the Global Real Time Ocean Forecasting System (RTOFS Global),

which became operational October 2011.

RTOFS Global provides ocean circulation forecasts for the global

ocean at 1/12th degree horizontal resolution and is a superior

product to the RTOFS Atlantic system that has not been upgraded

in more than 2 years. To streamline our products and optimize our

resources, NCEP would like to discontinue the legacy RTOFS Atlantic

system and migrate to RTOFS Global products.

RTOFS Atlantic output products were never made available on NOAAPORT.

They are only available on the NCEP ftp servers at:

ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/ofs/prod/

http://www.ftp.ncep.noaa.gov/data/nccf/com/ofs/prod/ofs.YYYYMMDD/

Output products include guidance for the U.S. coastal waters, including

the Eastern Seaboard, Gulf of Maine, Gulf Stream, and Gulf of Mexico.

Similar guidance is available from the RTOFS Global model. The products

from the two systems can be seen at:

http://www.nco.ncep.noaa.gov/pmb/products/rtofs/

Products from the RTOFS Global model are available on NOAAPORT and

also on the NCEP ftp server at:

http://www.ftp.ncep.noaa.gov/data/nccf/com/rtofs/prod/rtofs.YYYYMMDD

Where YYYYMMDD is the 4 digit year, 2 digit month and 2 digit day identifier.

NWS will evaluate all comments to determine whether to proceed

with this change. If approved, a Technical Implementation Notice will be

issued giving 30 days notice of the implementation date.
