| Zusammenfassung |
| Carbon dioxide (CO2) is the most important anthropogenic greenhouse gas and
causes global climate change. A large fraction of the anthropogenic CO2 is emitted
in and around highly populated urban areas including mega-cities. Seven years
(2003-2009) of global satellite nadir measurements in the near-infrared/shortwave-infrared
(NIR/SWIR) spectral region have been used to retrieve column-averaged mixing
ratios of CO2, denoted XCO2. This new multi-year global XCO2 data set will be
presented and it will be discussed to what extent and under which conditions regionally
elevated XCO2 resulting from urban area anthropogenic CO2 emissions can be
detected from space using data from the SCIAMACHY satellite instrument onboard
ENVISAT. |
