Just today, ASOS is carrying CLR with -RA. Winds were VRB05G15kt. I had to go in and sequence out the bad data.
Correct ob: FEW060 with winds only 13006KT

Over the last few weeks our ASOS has tried to carry 2 hundred foot ceilings when it was clear outside, not to mention the constant loss of the visibility sensor due to a small temp/dewpoint spread...and on and on and on...

Ours also does the 200 feet thing. So if you happen to be away from the OID, there goes a SPECI that starts getting raised eyebrows... If it happens, I suppose you would send a COR, which would look pretty strange also (a SPECI with no criteria). Sometimes ASOS leaves you with no good options.

All the time in Fla too. Whenever we get a downpour in the summer we see 3SM HZ P0010. Usually takes a few mins for the sensors to start carrying rain and sometimes an hour or more to stop carrying after it ends depending on how many frogs are in the tipping bucket

Let's see...in the transition plan...the FAA intends to go back to reporting clouds AOB 12K. This after recently putting in 25K ceilometers. Talk about a complete waste of money! Wonder how much these CL31's cost and how many were installed?

Those CL 31's don't work half the time.

Today our asos tried report wind gusts around 124 kt. Interestingly did not try to add a pk wnd remark. Real wind was a steady less than 10 kts.

My ASOS just put out a pressure change group of 58000. A human wouldn't do that, because according to the barometer tendency chart in the 7900; only codes of 0, 4 or 5 can be used if the pressure is the same as 3 hours ago. Has anyone else seen this?
I have noticed that it is hard to QC the APP before it is transmitted, since it often changes at the last second...

ASOS for some reason puts up the previous 3 hr APPP group until actual transmission. ASOS proly detected that the presuure was .04 mb or hectopascals lower than 3 hours ago. so it coded it as 0 change. just like a peak wind of 25.1 kts will show up in the peak wind group as 25. BUT 25.1 is greater than 25.0...according to ASOS...where as we humans say 26 kts for a pk wnd rmk because we don't measure to the nearest .1 mph
