Welcome to the Marine Modeling and Analysis Branch of the Environmental Modeling Center at the National Centers for Environmental Prediction in College Park, Maryland. We are responsible for the development of improved numerical marine forecasting and analysis systems within the NOAA National Weather Service.

Real Time Ocean Forecasting System (RTOFS)

NOAA WAVEWATCH III®

NOTICE OF PUBLIC RELEASE: A new version of WAVEWATCH III version 5.16 has been released. Details about the model and how to obtain the code can be found here.

A third generation wave model run four times a day (00Z, 06Z, 12Z, and 18Z). Each run starts with 9-, 6- and 3-hour hindcasts and produces forecasts of every 3 hours from the initial time out to 180 hours (84 hours for the Great Lakes).

Model Suite

Sea Ice Home Page

The Polar and Great Lakes Ice group works on sea ice analysis from satellite, sea ice modeling, and ice-atmosphere-ocean coupling. Our work supports the Alaska Region of the National Weather Service, the Great Lakes Marine Forecasting group in the Cleveland NWSFO, and other groups, as well as the Environmental Modeling Center, of which the ice group is a part.

NCEP SST Analysis

Because there are a number of different uses for sea surface temperature analysis, a number of different analyses have been developed at NCEP. The two families are the RTG -- Real Time Global, and the OI -- Optimal Interpolation (aka Reynolds SST). The RTG analyses are aimed at weather prediction and modeling, particularly at high resolution and short range. The RTG analyses employ a 2DVAR analysis technique. The OI analyses are lower resolution and aimed more at long range weather and climate. Both have a history.
