Ground Observations

Masks

Hundreds of observation stations are built throughout the French territory, each one fitted with several sensors measuring parameters such as temperature, pressure, wind... Each parameter is measured every 6 minutes and each file contains 1 month of data for each geographical area ('NW' for North-West of France and 'SE' for South-East of France).
