APCG is active in the testing and optimization of innovative air quality monitoring solutions which use low- and medium-cost smart sensors. IERSD/NOA is participating in the EMISSION national project, which aims to establish a network of monitoring sites in the area of Athens, utilizing sensor clusters. The network’s objective is to report air quality data to the public, in near real-time, via an integrated IoT online platform. Due to inherent uncertainties in sensor-based measurements, inter-comparisons and calibrations are systematically conducted using collocated reference instruments of the Thissio supersite and of the Mobile Air Quality Monitoring Station.

The APCG will operate 7 AQMesh medium-cost monitoring systems for concentrations of PM2.5, PM10, CO, NO2, O3. In cooperation with the University of West Attica, also under the EMISSION project, a custom-made low-cost system has been designed, based on electrochemical sensors for monitoring of ΝΟ2 and Ο3 and optical sensors for PM2.5. It is projected that more than 10 low-cost systems will be installed at sites around the Athens basin. In addition, a network of low-cost PM2.5 optical monitors started operating in 2019 by APCG at residential locations in Athens, in the framework of the National Research Infrastructure PANACEA (Panhellenic infrastructure for atmospheric composition and climate change), with data disseminated online in real time and visualized using an air quality index.

APCG also utilizes numerous portable instruments, which can be used for mobile and personal monitoring, in order to improve the characterization of the population personal exposure. Instruments include multi-wavelength portable micro-aethalometers for black carbon measurement and source apportionment, optical counters for measurement of particle number and mass concentrations in multiple size ranges, passive samplers for gaseous pollutants etc.
