Impact of long-lived pollutants on air quality and climate | 2021-2022

Tracking the progress on emission reduction of greenhouse gases and pollutants, identification of unknown sources, regular monitoring, reporting and verification of emissions. Visualise various satellite data alongside emission inventory data.
New compact remote sensing instruments for greenhouse gas measurements are crucial to fill gaps in the existing networks.
Nitrous oxide N2O is the third most important anthropogenic greenhouse gas. We retrieve the concentration from satellite observations providing global data twice per day.
Surface observations of CO2, CH4 and CO are dominated by local emissions and dynamical processes, while column observations are influenced by larger-scale mechanisms.
