Hourly frames are ERA5 analyses: the state of the atmosphere at that hour, not an average of the day around it. ERA5 is the ECMWF reanalysis produced for the Copernicus Climate Change Service; the newest days come from ERA5T, the preliminary stream, and are redrawn when the final one replaces them.
Generated using Copernicus Climate Change Service information. The map viewer is the Forecast Network's shared explorer, from Forecast Eagle.
