| Zusammenfassung |
| The passive airborne remote sensing grating spectrometer MAMAP (CarbonMapper) was
designed for measuring columns of methane and carbon dioxide (CO2) in the absorption
bands around 1.6 μm with an instrument precision of typically about 1% or better
relative to background. For the data under consideration the aircraft altitude was fairly
constant at 1250 m with a velocity of 200 km/h resulting in ground scenes of 30 m Ã
35 m.
Detailed analysis results in accurate emission rates for CO2 from point sources provided
that sufficiently accurate knowledge of the meteorological parameters, such as wind velocity
and atmospheric stability, are available. At the example of the two German coal fired power
plants Jänschwalde and Schwarze Pumpe two basic inversion approaches – a gaussian plume
model inversion and a simple gaussian integral inversion – are performed and evaluated in
terms of stability and accuracy in comparison with the actual emissions reported by Vattenfall
Europe.
The inversion approaches presented here have the potential to be used also for high
resolution satellite data with sufficient coverage as for example the proposed greenhouse gas
satellite mission CarbonSat would provide. |
