2020 Report
Atmospheric variables were measured in 2020 at the European Commission Atmospheric Observatory in the JRC site if Ispra (IT) to continue the assessment of the impact of European policies and international conventions on air pollution and climate forcing that started in 1985. Measurements included greenhouse gas concentrations (CO2, CH4), radon (222Rn) activity, short-lived gaseous and particulate pollutant concentrations (CO, SO2, NO, NO2, O3, NMHCs, NH3, PM2.5 and its main ionic and carbonaceous constituents), atmospheric particle micro-physical characteristics (number concentration and size distribution) and optical properties (light scattering absorption and extinction coefficients in-situ, light scattering and extinction vertical profiles remotely), and eutrophying and acidifying species (sulfate, nitrate, ammonium) wet deposition. On-line measurements data are visible in real time at abc-is.jrc.ec.europa.eu. Validated measurements can be retrieved from the ICOS, ACTRIS and EMEP data banks.
Vegetation - atmosphere exchanges (CO2, H2O and heat) were measured at our Mediterranean Forest Flux Station of San Rossore, backed up by meteorological and pedological measurements.
No effect of the 2020 COVID-19 lockdown on CO2 concentrations could be detected, and the changes in short-lived air pollutant concentrations cannot be directly attributed to the lockdown.
Preliminary data suggest that he pine tree forest was a large net sink for CO2 in 2020 compared to previous years.
