UKMO operational systems


Product description

UKMO runs two systems, the NEMO FOAM and the GloSea coupled ocean-atmosphere modelling system. The NEMO FOAM system is based on the ORCA025 developed by Mercator Ocean and it outputs daily operational short-range deep ocean forecasts out to 5 days. Various data types are assimilated into NEMO including:

  • satellite SST
  • along-track altimeter SSH
  • in situ temperature and salinity data (including Argo floats)
GloSea assimilates in situ temperature and salinity in the same manner as FOAM to provide seasonal forecasts once a month.

Ocean parameters

The following real-time parameter analyses and forecasts of the Atlantic NEMO FOAM system can be found here:

  • Temperature
  • Salinity
  • Velocity
  • Sea surface height
Additionally, these same analyses and forecasts, but in delayed mode, plus others from the FOAM system can be found and downloaded here in the form of maps or gridded data. Click on NCOF Products and then FOAM.

The following are parameter outputs of the GloSea system

  • Monthly temperature forecasts
  • Geopotential height forecasts
  • Precipitation forecasts
  • Pressure forecasts
  • Global SST forecasts
All the GloSea products are available in the form of maps or plots.
