Interactive An interactive map showing surface verification scores for different centrescenters.

  • results for 2 m temperature, 10 m wind speed, and total cloud cover (yellow)
  • results for 2 m temperature and 10 m wind speed only (grey)

For more details about the scores, please refer to the page "Exchange of WMO surface verification scores"

The map follows the Observation alarm interactive map setup.
