In the framework of the FENNEC French ANR program, an aerosol monitoring station has been deployed at the meteorological station of In Salah, in the middle of Algeria (27°15'N; 2°30'E).  The experimental set-up was designed by the LISA and operated by the local technicians of the Algerian National Meteorological Office.  It includes a continuous monitoring of the surface dust concentration (Total Suspended Matter inlet), the dust size distribution and local meteorological parameters (wind speed and direction, air temperature and humidity) acquired with a 5-min time step.
