184 years ago today an extreme windstorm hit Ireland & the UK, known as the 'Night of the Big Wind'. This event was one of the most severe & damaging windstorms to ever hit these islands.

We now need some help to learn from this event... #Archives

We have found a surprising number of locations with barometer measurements of pressure during Jan 1839. This should allow us to build a reanalysis to inform about the risks of such events today.

But, are there other sources we have not yet found?

@ed_hawkins I am right now setting up a huge list of all voyages in the Frydendahl data (name and type of ship, first and last date, route and where to find originals and Frydendahl's transcripts). Now at box 3 of 8, so I will soon be able to answer your question...

We do have rather old pressure data from merchant ships (not yet digitised either), but I've only seen maybe a permil of the data so far. I can't say by heart when exactly these batches will be scanned. So stay tuned...
