Note

The octahedral reduced Gaussian grid has a slightly lower resolution than the corresponding original reduced Gaussian grid with the same number of latitude lines.  For example, the O640 grid has a resolution of ~18 km whereas the resolution of the N640 grid is ~16 km.

ENS Meteograms based on IFS cycle 41r2 test data can be plotted by choosing 'E-suite' under the Experiment tab on the interactive page ENS meteogram page provided under the ECMWF Forecast Charts page as shown in the screenshot below.
