Getting model orography for a particular place?

    Re: Clouds Bases

    If I understand correctly, both the Cloud Base and Cloud Tops layers are height above model orography, which is sort of like a low-resolution averaged altitude. Is it possible to look up what is the model orography for a point on the map, relative to AMSL?

    I do a decent amount of hiking in mountainous areas, and what I'd like to be able to guess is whether a hike will be within the clouds (and have almost zero visibility), or possibly get above the clouds (although I know the Cloud Tops layer doesn't necessarily correspond to visibility). For any hike I can easily find the AMSL of the highest point, and I want to convert that into the height above model orography, to see where the top point is relative to the Cloud Base and Cloud Tops.

    Here is the way to know the altitude of the model orography for a place

    Unfortunately this is only available for ECMWF model.
    An easier way to get this information should be nice, for all models.

    That's perfect, thank you so much!
