Fixed tower collecting:
At 20m: CO2, H2O, long wave and short wave radiation fluxes, 3D wind speed and direction ambient air pressure, temperature and humidity.
At 10m: 2D wind speed and direction.
At 2m: 2D wind speed and direction, ambient air pressure, temperature and humidity.
Beneath ground: soil temperature, temperature flux and pending site development soil profile water content.
