Surface pressure record reanalysis gives hypnotic view of history

The records from 1851-2008 that comprise version 3.2.9 of the International Surface Pressure Databank have been plotted in a video lasting just under 13 minutes, by Philip Brohan.

Brohan explains on the Old Weather blog that 1.4 billion observations are included - and he highlights the changes in shipping traffic caused by events such as the opening of the Suez Canal, and the two World Wars.

He also points out that many more observations exist worldwide, but are not so far available to climate science. The International Surface Pressure Databank currently contains observations from established international archives data recovered by the Atmospheric Circulation Reconstructions over the Earth (ACREand other organisations such as national meteorological services, and projects like ERA CLIM.
