AWOS

I recently listened to the AWOS at Kerrville, Texas, which said that the ceiling was at 1700 feet.

I've been away from flying for a while, (OK, a long while), but as I recall it, here in Canada, when they say that the ceiling is 1700 feet, that is above airport elevation. It seems that in the Micro$oft f/s, it is ASL.

That gave me a ceiling of about 83 feet (I made it).

Is it different in the US? Are the airport ceilings given ASL down there?

cloud bases in the US are always AGL (above ground level)

so if the ATIS reports SCT022 BKN045

There is a scattered layer 2200 feet above the elevation of the ASOS machine, and a Broken layer (ceiling) 4,500 feet above the ASOS machine's elevation
