Zusammenfassung |
Total column concentrations of methane have been retrieved from ground-based
solar absorption FTIR spectra in the near-infrared recorded in Paramaribo
(Suriname). The methane FTIR observations are compared with TM5 model
simulations and satellite observations from SCIAMACHY, and represent the
first validation of SCIAMACHY retrievals in the inner tropics using
ground-based remote sensing techniques. Apart from local biomass burning
features, our methane FTIR observations agree well with TM5 model
simulations. The comparison of the direct measured CH4/CO2 ratios by
FTIR and satellite reveals that the satellite can hardly detect methane
emissions of tropical biomass burning due to the used retrieval method. |
