| Zusammenfassung |
| CarbonSat was selected by ESA as a candidate for the 8 Earth Explorer Opportunity (EE8).
The objective of the CarbonSat mission is to determine natural and anthropogenic sources
and sinks of the two most important greenhouse gases, carbon dioxide and methane. The
unique features of the CarbonSat mission concept are that it offers a combination of
high spatial resolution (2 x 2 km2) and broad swath (240 km) to provide global
imaging of localised strong emission source areas such as large cities (Megacities),
landfills, power plants, volcanoes, etc. and to be able to separate anthropogenic
from natural fluxes. In addition, CarbonSat data will also quantify natural fluxes of
CO2 and CH4 (biospheric CO2, wetland CH4 etc.) and their changes, to better
understand these important sources and sinks and their sensitivity to a changing
climate.
CarbonSat aims to deliver global data sets of dry column mixing ratios of CO2 and CH4
with high precision (goal: CO2 < 1 ppm, CH4 < 9 ppb) and accuracy. Benefiting from
its imaging capabilities, CarbonSat will provide an at least one order of magnitude larger
number of cloud free measurements than GOSAT and OCO and one order of magnitude
better spatial coverage than OCO. The CarbonSat mission concept builds on the heritage and
lessons learned from SCIAMACHY (2002-2012), GOSAT (2009-present) and OCO-2 (2014
onwards) to make scientifically and strategically important measurements of the
amounts and distribution of CO2 and CH4 for biogeochemical and climate change
research.
CarbonSat entered industrial system feasibility activities in 2012, which are supported by
scientific studies and campaigns. The current status of the mission concept and selected
results from the scientific studies documenting the expected data quality and characteristics
will be presented. |
