Regarding AUTOmated METARs, the AIM says there are two different kinds
of automated stations: "AO1 for automated weather reporting stations without a precipitation discriminator, and AO2 for automated stations with a precipitation discriminator. (A precipitation discriminator can determine the difference between liquid and frozen/freezing precipitation). This information appears in the remarks section of an automated report. " Does anyone know the practical use of this nugget of AO1/AO2 information? For example, does it mean that an AO1 station reports -RA for light rain OR light snow? Thanks! |
