| Zusammenfassung |
| Carbon dioxide is the most important anthropogenic greenhouse gas. Its global increasing
concentration in the Earth’s atmosphere is the main driver for global warming. However, in
spite of its importance, there are still large uncertainties on its global sources and sinks.
Satellite measurements, if accurate and precise enough, have the potential to reduce
these surface flux uncertainties. At present, there are only two satellite instruments
orbiting the Earth which are able to measure the CO2 mixing ratio (XCO2) with
large sensitivity also in the boundary layer. These are SCIAMACHY (launched in
2002) and GOSAT (launched in 2009). Worldwide, several teams of scientists are
developing algorithms aiming to meet the challenging user requirements. The majority of
these groups take part in ESA’s climate change initiative (CCI) on greenhouse gases
(GHG) where there algorithms stand into competition. Within the presentation, recent
inter-comparison results will be shown focusing on global SCIAMACHY nadir observations. |
