• ENS day 11 - 15 will be run at the same resolution as ENS day 0 - 10.
• The current ENS overlap data provided from day 9 to 10 is discontinued. 
• Overlap data is provided from day 14 to 15 for ENS Extended.
• The horizontal resolution of the ENS re-forecasts will be increased to match that of ENS.
• The two ENS constant-resolution forecasts provided for calibration and validation purposes are discontinued.
• There will be no change in the number and definition of the pressure levels.
• There will be no change in the model level vertical resolution.

Latitude-longitude resolutions for atmospheric products provided in dissemination

HRES

• HRES products will be available at the base grid resolution of 0.1° and multiples thereof.
• For backwards compatibility, HRES fields will also be available at the compatibility grid resolution of 0.125°.
• All product grids that can be generated from the base grid (0.1°)  will be generated from that grid.
• Those grids that cannot be generated from the base grid will be generated with the compatibility grid (0.125°).
• For example, grids of 0.5° and 1.0° will be generated from the base grid;  grids of 0.25° and 0.75° will be generated from the compatibility grid.

ENS

• ENS products will be available at the base grid resolution of 0.2°and multiples thereof.
• For backwards compatibility, ENS products from will also be available at the compatibility grid resolution of 0.25° and multiples thereof.
• All product grids that can be generated from the base grid (0.2°) will be generated from that grid.
• Those grids that cannot be generated with the base grid will be generated with the compatibility grid (0.25°).

ENS Extended

• ENS Extended products will be available at the base grid resolution of 0.4°and multiples thereof.
• For backwards compatibility, ENS Extended products from will also be available at the compatibility grid resolution of 0.5° and multiples thereof.
• All product grids that can be generated from the base grid (0.4°) will be generated from that grid.
• Those grids that cannot be generated with the base grid will be generated with the compatibility grid (0.5°).
