The data presented are collected on-line from the Meteorological & Actinometric Station of the IERSD-NOA, located on the Hill of Koufou at Penteli area.

These data are updated every 10 minutes.

(1) The value of the atmospheric pressure refers to the average height of the sea surface.
(2) The value of the cumulative precipitation is reset to zero at 08:00 and at 20:00 every day.
(3) The values of the illuminance and irradiance are referred to horizontal plane.
(4) The wind measurments are at 10m above the ground.

(5) The Heat Index estimation is only useful for air temperature > 26°C and rel. humidity > 40%. Otherwise is equal to air temperature.

(6) The Wind Chill Index estimation is only meaningful at wind speeds between 1 and 50 m/s and air temperatures between -45°C and 20°C. Otherwise is equal to air temperature.
