Storm Ciarán atmospheric pressure data

Storm Ciarán passed over the south of the UK on 2nd November 2023. This caused the atmospheric pressure to be unusually low for November, in the early morning in the south-east of the UK. This archive contains a collection of pressure measurements assembled for the region most affected. Data from roadside measurement sites at southern UK sites form the majority of this archive, at 10min sampling. The archive includes measurements at 1sec resolution obtained from the University of Reading Atmospheric Observatory’s precision barometer data, and from two amateur sites (Selsley and High Littleton) in the south-west. Boiling point of water determinations from Reading are also included.
