> Why are you subtracting the in Bologna if it was actually measured there? no, they measured it a bit away, but still in Bologna. I you want the precise position, I may tell you that later, I have access to all the historic weather data. I think it is the airport there. Meteorology was my business for a long time. Every station transmits the local air pressure and adds the lacking pressure that comes from local height above sea level. See wikipedia "barometric formula" for details, its about 1 hPa per 8 m. If every station of the world would simply transmit local air pressure, you would not be able to draw the ground pressure charts. All values are sl-values. -- NEU: FreePhone - kostenlos mobil telefonieren! Jetzt informieren: http://www.gmx.net/de/go/freephone
