ECN Meteorological Data recorded Graphs

Various meteorological data have been recorded hourly from January 1993. They are mainly separated into 4 groups :

Temperatures: Air and soil temperatures.
Radiation: Radiation and albedo measurements.
Rainfall: Rainfall and humidity variables.
Wind: Wind direction and wind speed.
