To limit global warming to well below 2C compared to pre-industrial levels requires a decarbonization of the economy and many countries have pledged to reach net-zero emissions by 2050 but progress has been slow so far. Satellite observations of CO2 and CH4 will play a key role for tracking progress towards emission reduction targets and for verifying the effectiveness of mitigation policies. Satellites also provide information on natural sinks which store large amounts of carbon and play a potentially important role in the pathway towards net-zero emission.
In this presentation, I will introduce the key concepts for satellite observations of CO2 and CH4 and present examples how we use current, dedicated satellite missions to quantify regional surface fluxes of natural and anthropogenic sources. I will discuss how such dedicated missions can be complemented by hyperspectral satellites with high spatial resolution that allow constraining individual emission sources. The presentation will end with an outlook to the upcoming Copernicus CO2 Monitoring (CO2M) Mission, the space component of the European anthropogenic CO2 Monitoring & Verification Support Capacity.
