| Zusammenfassung |
| CO2 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 sources and sinks: What is their global
distribution? What is their temporal evolution? How will they behave in a changing climate?
Satellite measurements, if accurate and precise enough, have the potential to reduce such
surface flux uncertainties.
SCIAMACHY started its operation in 2002 with the launch of ENVISAT. Roughly one
decade later ESA declared end of the mission due to the unexpected loss of ENVISAT.
SCIAMACHY was the first and during seven years the only satellite instruments which was
able to measure the CO2 mixing ratio (XCO2) with large sensitivity also in the boundary
layer.
Therefore, SCIAMACHY measurements are essential to create a consistent long term
climate data record of XCO2 measurements. We will present two datasets (WFMD and
BESD) each of which covering the full SCIAMACHY time series. Analyses of the datasets in
respect to land-atmosphere interactions and long term trends will be part of the
presentation. |
