Air pressure - Kiel - last month
At our station the air pressure (in German: Luftdruck) is measured with a digital sensor BMP280, Bosch-Sensortec, Reutlingen, DE.
The horizontal line at 1013 hPa marks the global annual average of the atmospheric pressure at sea level.
The black curve in the picture "last year" represents the moving average of the air pressure over 14 days.
On the X axis the time ME(S)Z means Central European (Summer) Time CE(S)T.
