Short summary

We evaluate the ability of the Vaisala AQT530 (Air Quality Transmitter) monitors, comprising of low-cost sensors, to detect spatial and temporal differences. Collocated with reference instruments over 19 months in Nicosia, results showed that CO and PM (particulate matter) sensors captured daily, hourly, and monthly spatial trends. NO₂, NO, and O₃ sensors were less reliable due to environmental effects. Still, all sensors tracked monthly temporal variations at the same location, with PM_2.5 showing the strongest agreement with reference data.
