@Nelson-Neault said in Model grid:
because the information is not available to Windy. Too bad, but can't argue about that.
No, the information is available TO Windy, but it is not shown in Windy as a layer. Some weather apps display the grid of the models they use.
The grid as you say could be displayed asl but with the topography model added. Like this example with GFS

If you know this area in the French Alps, GFS “considers” the Mont-Blanc (4807m) at only 2030m high. This is because of its 22km low resolution.
So your request would not be impractical.
