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.
