The micrometeorological station is intended to give complete information about the surface-atmosphere transfer of momentum, heat and water vapour. It is composed by two units.

1) Telescopic mast with fast response instrumentation

It is a 6-elements telescopic mast of 16 m height in full extension, with 3 possible levels for instrumentation. In the upper level there are:

A Solent-Gill 20 Hz ultrasonic anemomenter, one Campbell Kh20 Krypton hygrometer, optically measuring water vapour turbulent fluctuations directly in open air  (‘open path’ instrument).

A surface temperature sensor Everest 4000.GL, measuring the radiative  surface temperature by a blackbody-like internal cavity.

A net radiometer (Seap-Micros Radnt), measuring the difference between the total (short and long wavelength) radiation emitted from the sky and from the earth  surface. It is based on a thermopile system, sensitive to temperature differences between the upper and lower sides. The measured net radiative flux represents the available energy flux for evaporation, atmosphere and soil heating.

A slow response  thermohygrometer for the air temperature and humidity (Rotronic MP100).

Data are collected and processed by a dedicated notebook with a home-made software that allows automated statistical averaging (half-hour) in the ‘streamline’ coordinate system, with storage requiring little room in memory and format being suitable for immediate micrometeorological interpretation and analysis.

2) Automated Meteorological Station.

It is equipped with standard meteorological sensors and soil data sensors.

Standard sensors: cup anemometer, thermohygrometer, global and net radiometers, rain gauge, barometer.

Soil sensors are devoted to collect temperature, moisture and heat flux data at 2 levels (2cm and 30cm depth):


2 thermistor temperature sensors (Campbell108L)

2 moisture content capacitive sensors (Decagon EC-5)

2 thermopile soil heat flux sensor (Hukseflux)


Data are acquired and half-hour averaged on a dedicated datalogger (Campbel CR10-X) solar energy powered and expanded with a multiplexer.
