| Zusammenfassung |
| Carbon dioxide (CO2) and methane (CH4) are the two most important anthropogenic
greenhouse gases causing global climate change. Global satellite observations of CO2 and
CH4 can provide important missing global information on regional CO2 and CH4 surface
sources and sinks. A better understanding of the surface sources and sinks and the underlying
processes is important in order to reliably predict the future climate of our planet. Such an
application requires highly precise and accurate satellite CO2 and CH4 retrievals
and high sensitivity to near-surface greenhouse gas concentration changes. With
passive satellite remote sensing this is possible using reflected solar radiation in the
near-infrared/shortwave-infrared (NIR/SWIR) spectral region. SCIAMACHY on ENVISAT
is the first satellite instrument performing these type of measurements (launch 2002). The
SCIAMACHY time series is currently being continued with the Japanese GOSAT
satellite which has been successfully launched in January 2009. In order to fill a likely
observational gap in the post-GOSAT time period and to provide important additional
greenhouse gas information the Institute of Environmental Physics (IUP) of the
University of Bremen in collaboration with many partners is currently conducting studies
for a future greenhouse gas satellite mission called "Carbon Monitoring Satellite"
(CarbonSat). CarbonSat will be proposed to ESA by IUP as an Earth Explorer Opportunity
Mission. In this talk an overview about the latest achievements of SCIAMACHY and
GOSAT will be given and the mission goals and mission concept of CarbonSat will be
presented. |
