This animation shows the weather and surface marine observations over the Europe-Atlantic area for the year 2018.
Each of the 24 frames per second shows, for a given date and hour, contours of 6-hour averages of mean-sea-level pressure from ERA5 (generated using Copernicus Climate Change Service information 2019), as well as locations of all observations from buoys or ships or fixed platforms received within +/- 12 hours.
