Atmospheric pressure is measured by a Bosch BMP085 digital sensor. Each sensor is individually calibrated and should be accurate to ± 1 hPa.
The equivalent sea-level pressure is also tabulated (but not plotted); this is derived using Babinet's formula from the height above sea level and the local air temperature. The local height above sea level and the sensor to use for temperature are specified in the UserDB. The defaults are zero and 10° C.
Station height 70 m asl. Air temperature 10.0 °C
Atmospheric pressure over the last 24 hours
