Since 5 April 2011, the atmospheric research station is up and running. The measurements for the optical properties of atmospheric aerosols during the period 07/04–17/05/2011 are presented. The blue line corresponds to the scattering of light by the particles while the red to the absorption at visible wavelengths. Please note the different scale in the two axes. What is worth noticing is an event which took place on 1 May. During that day, a so called “Sahara dust event” resulted to the transport of great amounts of dust particles from the arid areas of the Sahara desert towards Eastern Mediterranean. That was obvious in the data for light scattering, a spike in the nephelometer data for that day. Calculating air mass back trajectories (using HYSPLIT model of NOAA) for that particular day, meaning calculating the origin of the measured air masses, it was obvious that the air arriving at Costa Navarino came from Sahara desert (upper panel of figure).
