The table below shows the latest meteorological measurements of the ExWi weather station (46° 57' N, 7° 26' E, 575 m asl) of the Institute of Applied Physics of the University of Bern. The values are updated every minute. Due to the data transfer there is usually a delay of two or three minutes. Note that the time is in UT.

Explanations

In general, instantaneous, average, maximum and minimum values are displayed. The time period for the average, maximum and minimum values is one hour, except for wind speed and direction, where the period is two (superscript 2) or ten minutes (superscript 10). Also the visibility average value is over ten minutes. QNH and QFF are pressures normalized to sea level, the first with a standard temperature of 15°C and the second with the actual temperature.

The rain and snow sensors provide an instantaneous value and a cumulative sum. The sum of the rain gauge is reset at 06:00 UT every day. The other two sums restart after 99.99mm (rain) and 999.99mm (snow).

The weather types are according to the WMO code table 4680.
