Help on how to interpret the maps

Close this window

Below are a few points that will help to interpret the maps on the website.

  • Each circle or dot on the map represents a station.
  • The legenda on the right of the map indicates what the colours mean. For example, on a trend map for precipitation amount, blue circles indicate a wetting trend while red circles indicate a drying trend.
  • On the trend and anomaly maps, the size of the circle gives a range for the size of the trend of that particular station.
  • Using the i-button and clicking on a station will give a pop-up with details of that station, including the value of the trend or anomaly, depending on the map.
  • The station density varies over Europe. This indicates that stations with data series available for the requested time period are not equally distributed over Europe. In some areas there are fewer stations or fewer stations which exist for a long time period. In other areas the ECA&D team does not have access to all available station series (often due to data policy differences between countries). Zooming in will make it possible to distinguish between different stations.
