aviation weather documentation shows that they check for 6 automated station types.
|auto_station||Indicates that the automated station type is one of the following: A01,A01A,A02,A02A,AOA,AWOS|
What are the automated station types their meaning and how to determine the automated station type from a Metar report?
The following table is what I have ascertained:
|auto station type||meaning||where to find in Metar report|
|AO1||automated station without a precipitation discriminator||there will be an AO1 after RMK|
|AO1A||automated station without a precipitation discriminator and manually augmented||there will be an AO1A after RMK|
|AO2||automated station with a precipitation discriminator||there will be an AO2 after RMK|
|AO2A||automated station with a precipitation discriminator and manually augmented||there will be an AO2A after RMK|
|Any other automated station types?||?||?|
