The Air Quality measurements are conducted at the urban-background “Air Pollution Monitoring Station” of the Institute for Environmental Research and Sustainable Development (IERSD/NOA)> at Thissio, central Athens.
The station is operated by the Atmospheric Chemistry and Physics Group (APCG) which acknowledges the H2020 SMURBS/ERA-PLANET project.

- Two key dates for COVID-19 measures should be considered. March 15th as the start of the first mitigation guides and March 23rd as the date of the general lockdown. For the calculation of percentage changes, we use the first date. Changes are calculated in relation to i) the average concentration measured since the beginning of the year, ii) the average concentrations during February.
- The PM2.5 measurements are conducted with optical particle counting/sizing instruments, calibrated using a reference-equivalent monitor. In case of dust transport events, reported concentrations may significantly deviate from actual ambient concentrations.
- To evaluate the temporal variability of concentrations in association with the adopted “lockdown” measures, climatological and meteorological factors should also be taken into consideration.
