1/8° Global NCOM Nowcast

Please note: Global NCOM was retired on 5 April 2013 and replaced by operational 1/12° HYCOM. Users should transition to
Real-time 1/12° Global HYCOM Nowcast/Forecast System

We at NRL SSC would like to be continually involved with any uses of the data or graphics that we provide. Please keep us informed of any transitions or publications. Please let us know immediately if you should see anything questionable in the data or graphics so that we can make the product better.

Plots of operational global NCOM changed from version glb8_2f to version glb8_3b on 1 June 2008. The upgrade from glb8_2f to glb8_3b included addition of MLD-modified synthetics for assimilation, profile assimilation via NCODA, coupling with the CICE 3.0 ice model, and use of NCOM version 4.0

    This site contains real-time nowcast results from the 1/8° global version of the Navy Coastal Ocean Model, including snap shots and animations for many zoom regions, mainly Sea Surface Height (SSH), Sea Surface Temperature (SST) and Sea Surface Salinity (SSS). In addition, this site contains links to the 1/16° global NRL Layered Ocean Model (NLOM) and the 1/8° global Modular Ocean Data Assimilation System (MODAS), again with SSH and SST snapshots and animations for many zoom regions, plus a link to the Real-time Ocean Environment page that includes plots of the real-time altimeter data available.

    The 1/8° global NCOM is run daily at the Naval Oceanographic Office (NAVOCEANO) with atmospheric forcing from the Navy Operational Global Atmospheric Prediction System (NOGAPS) and assimiltion of SST and synthetic temperature and salinity profiles via the MODAS climatology based on input from the operational 1/16° NLOM SSH and 1/8° MODAS 2D SST nowcasts. This web page is updated daily by NRL and should be considered a demonstration product. We do not guarantee availability, service, or timely delivery of data.

    NRL and NAVOCEANO are participants in the multi-national Global Ocean Data Assimilation Experiment (GODAE) including presence on the U. S. and international steering teams. GODAE is aimed at demonstrating real-time global ocean products in a way that will promote wide utility and availability for maximum benefit to the community.
