Tonga eruption atmospheric pressure wave data

How to cite this Dataset

Description

The eruption of the Hunga volcano on 15th January 2022 generated a pressure wave which propagated around the world multiple times. Its passage was recorded at the University of Reading Atmospheric Observatory in the routine precision barometer data. Using additional data from roadside measurement sites, the initial pressure disturbances could be seen to propagate north-south across the UK (having travelled via the north pole), and subsequently south-north (having travelled via the south pole). The first passage at Reading disturbed the low cloud which was then present. Subsequent passages of the pressure wave diminished in amplitude. This archive contains the roadside atmospheric pressure data, and the Reading University atmospheric pressure and cloud base data.
