Final Approach
Yep, really. It's pretty consistent from what I've seen, and I'm not sure why. I've thought maybe with cumulus clouds the sensor picks up the bases as a SCT layer, but sometimes there's no SCT layer reported, just BKN or OVC and the bases are much lower.Really? I've found most AWOS/ATIS to be pretty on target with bases.
As I posted on the Red Board this morning, I think most automated stations are just plain unreliable but I could see where someone might get the impression that the AWOS was reporting MSL not AGL. I once scud ran into KGLR with about a 1300' ceiling that was being reported as 2500' by the on-field AWOS. Since the field elevation is 1328 MSL, that would have actually been about right.
But it sounds as if the ones near you are more accurate.
