Dear Windy.tv Team,

I have the same question that rjeff already asked a while ago (but which I didn't find to be answered, yet):
In case of e.g. wind, what does the height mean exactly. I understood that ground level means 10m above ground and other heights use sea level as reference.
But:
What if I am looking for wind data in the mountains? In that case you also provide wind data for e.g. 100m (above sea level) which is below the ground.
I feel, as long as surface height is not reached, there should be empty spots on the map.

I'd be greatful for your response!
Cheers,
Hecky
