PI: Dr. Eleftheriadis Konstantinos ( Operators: Dr. Fetfatzis Prodromos (

Permanent HAC station instrument: Continuous Particulate Monitor (BAM1020)

The BAM 1020 automatically measures and records PM10 airborne particulate concentration levels  in milligrams or micrograms per cubic meter.  It uses the principle of beta ray attenuation and was installed at Helmos Mt. since 11/2018. It has hourly data recording time step, hourly filter progress and automatic span calibration checks.
