I had the same question e.g. about cloud base, about whether it is cloud over the high ground, or cloud above sea level. Height above sea level would be more useful information for estimating what's going on...
No we do not adjust interpolated values to its terrain height (interpolation in between two model levels). @TZ did some coding in this field but not finished it yet.
We do not have ANY METEOROLOGISTS in Windy team which is shame (the one I would love to have in team is Swiss), therefore we lack a knowledge in this field. If you have suggestions how to interpolate model's parameters to terrain height, please let us know. Send us some formulas to use or some document how to do it please.
So that I understand what you are saying, could you please confirm:
the elevation in "about location" of 2113m NOT the elevation for the meteogram forecast immediately to the left of that information?
the elevation in "about location" of 2113m refers to the elevation of the spot position on the map topography (my visual check confirms it is always pretty close)
the meteogram forecasts do not adjust their values for elevation of the spot position on the map?
the meteogram forecasts are based on a wide grid, which can result in a high peak displaying data for a low valley that falls within the same grid.
