Results depicted on these web pages are from the operational 1/32° global NLOM nowcast/forecast system. This system became operational on 6 Mar 2006 as an upgrade to the 1/16° global NLOM system that ran operationally at NAVOCEANO from 27 Sep 2001 - 5 Mar 2006. Overall, the 1/16° NLOM ran in real-time 18 Oct 2000 - 11 Mar 2006 and was discontinued 12 Mar 2006 and the 1/32° NLOM has been running in real time or near real time since 1 Nov 2003 and these results are archived on the corresponding web pages along with hindcast results extending back to 1993, mostly on the 1/16° NLOM web page. The model presently is assimilating SSH from 3 satellite altimeters (ENVISAT, JASON-1 interleaved and JASON-2) and sea surface temperature from satellite IR imagery. Altimeter track data over a 3-day window are assimilated each day. Nowcasts are run daily and 30-day forecasts are presently run once per week.
