September’s edition of the Royal Meteorological Society journal, Weather, features a paper (lead author, Matthew Lickiss) on the development of our quick guide to presenting data and uncertainty. The guide was developed during the large, NERC-funded project RACER, in which our part was a collaboration with meteorologists on the communication of the risk and uncertainty of extreme meteorological events. While our research covered people’s use of information in decision-making across scenarios ranging from volcanic ash to impassable ice, the guide (downloadable here) presents very basic principles, applicable to all data communication.
