I don't expect many replies on this, but I've been hearing ATC comments and seeing for myself at NavCanada's weather info, and noticing these AWOS's like those at Toronto Island, Muskoka, Moosonee, Eartlon, etc... always report 2 + layers of an overcast ceiling, or rain (-RA) under CLR skies, etc. Does anyone have information on these robotic equipment pieces out there around the world? lol.
