It's in just about every US METAR. According to Aviation Weather Services AC 00-45E, "Some stations also include the sea-level pressure (which is different from altimeter). It is shown in the Remarks element as SLP being the remark identifier followed by the sea-level pressure in hectopascals (h/Pa), a unit of measurement equivelent to millibar (mb).And in reading in it, AO2 is infact the automated observation with percipitation discriminator.----------------------------------------------------------------John S.

CLR means no clouds below 12000' The European equivilent is CAVOK (Ceiling and Viz OK) which means no Cumulonimbus at all, no cloud below 5000' and viz > 9999 meters.I had to look this one up (http://www.asy.faa.gov/safety_products/metar-taf99.html): RMK AO2 SLP196 T01830044 53003 = Remark: Sea Level Pressure 1019.6 millibars (or hectopascals) Temp 18.3 Dewpoint 4.4. The A02 means an automated observation taking into account precipitation. A01 is automated but not taking into account precipitation. The P6SM means more than 6 stat miles. Anything over 6 won't be reported. Similar to 9999 meters for European METARs/SPECIs/TAFs

thanks for the info guys! It looks like it is time to get out of europe and do some flying :)cheers,Claudio
