Automated Weather Observing Systems

AWOS- Automated Weather Observing System.
ASOS- Automated Surface Observing System.
AWOS-3 reports all the items in a METAR – time of observation, wind, visibility, sky coverage/ceiling, temperature, dew point and altimeter setting. The designator "A02" in the remarks portion of the observation indicates the station has a precipitation discriminator that determines the difference between liquid and freezing/frozen precipitation.
ASOS reports the same data as AWOS-3 plus precipitation type and intensity like the AWOS-3 sites with the A02 capabilities.
AWOS-2 reports the same METAR items as an AWOS-3 except it does not report sky coverage/ceiling information.
AWOS-1 reports the time of observation, wind, temperature, dew point and altimeter setting. It does not report visibility or sky coverage information.
AWOS-A reports only the time of observation and altimeter setting.
The prefix "AUTO" indicates the data is derived from an automated system.  A certified weather observer may provide augmented weather and obstruction to visibility information in the remarks of the report at AWOS locations.  
The "AUTO" prefix disappears when the report has been augmented by human observers.

If you are facing:  Adjust baseline personal minimums to: 
Pilot  Illness, medication, stress, or fatigue; lack of currency (e.g., haven’t flown for several weeks)  A d d  At least 500 feet to ceiling 
At least . mile to visibility 
Aircraft  An unfamiliar airplane, or an aircraft with unfamiliar avionics/ equipment:  At least 500 ft to runway length 
enVironment  Airports and airspace with different terrain or unfamiliar characteristics  S u b t r a c t  At least 5 knots from winds 
External Pressures  “Must meet” deadlines, passenger pressures; etc. 

Step 4: Assemble and evaluate baseline personal minimums.
