A meteorological station and a flow tower have been installed in the Kamech watershed. Through these two stations, a set of sensors is arranged to collect various meteorological variables.

The meteorological station, installed in 1998, is equipped with sensors that are placed two meters above the ground. These sensors allow the acquisition of global radiation, wind speed and direction, air temperature and humidity, atmospheric pressure. The instruments used are: pyranometer, anemometer (A100R, vector), wind vane (W200P), thermohygrometer (HPM45C, vaisala), barometer (CS100, Setra).

The flow tower or micro-meteorological station, installed in 2010, is equipped with sensors installed at 10 meters from the ground, allows to measure the real evapotranspiration (ETR) by the turbulent covariance method. This method is based on high frequency measurements (10 to 20 measurements per second) of vertical wind speed, air temperature and air humidity. The instruments used are: sonic anemometer (CSAT3, Campbell Sc), icor 7500, air temperature and humidity (HMP45, vaisala). Additional sensors measuring temperature, relative humidity and speed are installed at 2 m height from the ground allowing to have a second point of measurement of the meteorological variables on the BV.

A data acquisition system calculates and stores the average values over 30-minute time intervals. The data are collected by the staff of INRGREF of Tunis. They are processed, prepared in the format of integration in the database HYSAE of LISAH to be integrated into the information system of OMERE

Through the OMERE data web portal, the address of which is given in this fact sheet, the data can be consulted and downloaded.
