GRIB Model

Mercator Global - Ocean Currents

Provider:Mercator Ocean International via CMEMS.
Model scope:Global
Update frequency:every 24 hours
Resolution:0.08°, 4.8nm, 8.9km
Model duration:33 forecasts starting at 12 hrs, ending at 10 days
Parameters:current, water temperature
GRIB model date:Sat Dec 9 23:30:00 2023 UTC
Download date:Sun Dec 10 13:36:06 2023 UTC
Download delay:14hr 06min

Note: the Download delay is the amount of time required for the GRIB model to compute its forecast and then for the LuckGrib cluster to download the data and make it available. The LuckGrib delay is generally less than 10 minutes, the remainder of the delay is the model compute time.


This is the Mercator Océan International global ocean current model, providing 10 days of forecast data at 1/12° resolution.

This data is generated using E.U. Copernicus Marine Service Information which, in turn, is obtained from Mercator Océan International.

The Operational Mercator global ocean analysis and forecast system at 1/12 degree is providing 10 days of 3D global ocean forecasts updated daily. …

This model is refreshed daily at around 14:00 UTC.

Note that you may also find this data referred to as MyOcean by other services. The history of MyOcean, Copernicus and the Mercator global ocean current model can be found at the MyOcean Wikipedia page.

Note on forecast times

The Copernicus site providing this data has many different versions of the Mercator model, over a dozen versions. Some of the data is indicated as being instantaneous and the rest is marked as being the mean (average) over various time intervals. For example, there is one version of this model which offers forecasts for the daily average current, or the six hourly average.

The data being downloaded with the LuckGrib Mercator is the hourly mean (average) version of the model. This is reflected in the forecast times in the data. For example, you will see forecast hours such as 11:30 UTC, 3:30 UTC, etc.

For example, the data associated with a forecast time of 11:30 UTC is the hourly mean across the model for the times 11:00:00 UTC to 11:59:59 UTC.
