METAR reports list cloud ceilings Above Ground Level (AGL), not above mean sea level (MSL). So if the airport is 500'AGL, and the METAR reports "bkn120", then the cloud ceiling would be 12,000 feet above the ground and 12,500 MSL. Does ASE depict the cloud ceiling accurately, i.e. AGL?

Hi,With B572 clouds at airports with actual data are correct. If an airport has advanced interpolated data, then it is possible that the clouds are not at the correct altitude and this is on the fix list for a future SP.

Thanks for the reply, Jim And I noticed that I had a typo in my first post. I meant to say, "So if the airport is 500' MSL", not "500' AGL". Can't imagine an airport being 500' AGL. That would be quite a trick. :(
