  2. This video shows four things:
    1) The weather - the mean-sea-level pressure as simulated by the 20th Century Reanalysis (black contours: solid=low pressure, dashed=high).
    2) The observations - grey circles mark observations that we've had for a while, yellow ones observations recently recovered by the ACRE and oldWeather projects.
    3) The fog of ignorance - grey fog masks regions where the reconstructions are still very uncertain (as there are too few observations to constrain the reanalysis).
    4) The glow of discovery - yellow highlights mark regions where the new observations have produced a large improvement in the confidence of the reconstructions.

oldWeather (oldweather.org) has been reading the logbooks of Royal Navy ships from the period 1914-1923 - extracting the weather observations they contain for the benefit of present-day climate research, and extracting other events recorded in the log for the benefit of historians.
Each video shows the log of a single voyage, marked-up with the information transcribed by the community of volunteer researchers on the oldWeather website.
