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.
