METARs from an airport will always have the altimeter setting, because that’s what pilots care about. At least in the US it is given in hundredths of an inch, prefixed with “A”. For example KWVI 130053Z AUTO 00000KT 10SM CLR 13/07 A3031 RMK AO2 SLP263 T01280072 the altimeter setting is 30.31”. METARs usually also contain the pressure corrected to sea level; that’s the string that begins with “SLP” and gives the pressure in tenths of a millibar, without the hundreds and thousands digits. “SLP263” = 1026.3 millibar. (Note that the 30.31 altimeter setting in that METAR corresponds to 1026.5 mb, so they really are different values.) -Les -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
