Sure?

closest station is 

http://www.findu.com/cgi-bin/raw.cgi?call=EW0301

presently reporting 

EW0301>APRS,TCPXX*,qAX,CWOP-3:!4002.66N/07527.34W_319/002g010t042r000P000p000L000h62b10150.VWS-DavisVP2+

The baro pressure is 5 digits following lower case b, or 10150, which sure looks like Pa / 10 (or hPa x 10) to me.

next closest is W3HOA-2, reporting 10156

In fact, of the 20 closest, the only one with data that appears bad is N3NTP-2.
