- Each partner will provide their eps data on a 1.5/1.5 regular lat-lon grid for both ocean and atmosphere. First grid point is 90N 0E. The data will be archived first from east to west (OE to 358.5), and then from North to South (90N to 90S).
- Grids are defined in GRIB2 using an accuracy of 1/1000000 (one millionth) of a degree. If this accuracy is not sufficient to describe your grid (latitude/longitude of first and last points, as well as grid increments) without loss of information, you can use a GRIB2 feature that provides a way to describe any regular grid. See the page on encoding global latitude/longitude grid for more details.
Ocean parameters
- follow the same rules but the data is on a 1.0/1.0 regular lat-lon grid
Number of forecasts
- The Control Forecast must be number 0,
- The number of members is identical to the number of all EPS members plus the Control Forecast.
