5. Ocean Analysis Products

The ECMWF ocean analysis system produces daily analysis of the global ocean for temperture, salinity, velocity, sea level and other derived variables.The reanalysis stream spans the period 1959 up to 11 days behind real time. The realtime stream started it August 2006.

The following products are displayed in the web:

• Horizonal maps of SST, Sea Level, Depth of 20 deg Isotherm, Surface Salinity, Zonal Wind Stress and Averaged Temperature and Salinity over the upper 300m.
• Zonal sections along the equator of temperature.
• Meridonal temperature sections at 165E, 140W and 30W.
• Time-Longitude sections along the equator of SST, Sea Level, Depth of 20 degrees Isotherm, Zonal Wind Stress.
• Observation coverage maps and quality control decisions.

Both the full fields and the anomalies respect the 1981-2005 are displayed. The maps represent daily fields from the real-time analysis, and weekly and monthly from the reanalysis stream. The monthly fields go back to 1959. The weekly fields are only displayed since January 2007. For the realtime, only the last 30 daily fields are displayed.
