4 1. INTRODUCTION In the frame of the POSEIDON Project, the Laboratory of Atmospheric Physics of the University of Patras performed continuous monitoring of PM measurements at the area of the new (south) port of Patras. The measurements had started on October 2013, in the frame of the CESAPO project (ETCP Greece Italy, ) ( and continued in the frame of POSEIDON. Measurements were performed using the Environmental Dust Monitor #180 of Grimm Technologies Inc, that belongs to the Environment Laboratory of the School of Natural Sciences of the University of Patras. The location of the monitoring equipment is shown in Figure 1.1. Figure 1.1. PM monitoring equipment at the south Port of Patras (photos: courtesy Ing. Spyros Crotsis) The monitoring equipment measures continuously the concentrations of PM 10, PM 2,5, PM 1 (in µg.m -3 ). The sampling air flow is set at 1.2 L.min -1. Measurements are stored as ten-minute averages; a database with the measurements is available. The following report provides a short overview of the complete time series. Monitoring started on and is ongoing. There is a gap starting March 11th, 2015, 10:24:00 UTC until April 8th, 2015, 11:13:00 UTC. During this period the sampler had to be shipped to Athens for the regular maintenance and recalibration. 4
