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

Methane emissions in Belgium
A look at the emissions behind the satellite data
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.
Compact solar tracker system
Assessing new remote sensing platforms for GHG reference measurements
New compact remote sensing instruments for greenhouse gas measurements are crucial to fill gaps in the existing networks.
World map N2O average partial column 2019
N2O, a less known greenhouse gas now monitored from space
Nitrous oxide N2O is the third most important anthropogenic greenhouse gas. We retrieve the concentration from satellite observations providing global data twice per day.
Map column-averaged concentration of CO
Sources and sinks of long-lived greenhouse gases at Réunion Island
Surface observations of CO2, CH4 and CO are dominated by local emissions and dynamical processes, while column observations are influenced by larger-scale mechanisms.
