# Oscillation in pressure sensors

The barometers in the [Wind Tunnel Mk2](/the-chambers/wind-tunnel-mk2.md), which produce the sensor measurements `pressure_upwind` , `pressure_downwind`, `pressure_intake` and `pressure_ambient`, are all affected by the ambient atmospheric pressure.

[Here](https://barometricpressure.app/zurich) you can track the atmospheric pressure in Zürich, where our chamber farm is located.
