This is a map of all meteorological stations as running at the end of 1939, for which station numbers and acquisition dates could be found. The data presented includes all stations (which at a minimum measured precipitation) and those which also include temperature measurements. However, the lack of temperature measurements did not necessarily mean that no other measurements were made. The existence of the station in 1939 does not guarantee it’s continuous operation (as indicated by the end year).
As the COBECORE project has only a limited running time we will focus on those locations which combine both precipitation and temperature measurements (and all other observations made if they exist at the respective stations).
