Seasonal an latitudinal variations of column averaged volume mixing ratios of atmospheric CO2

Description : Column-averaged volume mixing ratios of CO2 have been obtained by ground based high-resolution solar absorption spectrometry at Ny-Alesund (Spitsbergen, 79°N) in 20022003 and during two ship cruises (54°N34°S) on the Atlantic in 2003. Precisions are better than 0.4% at Ny-Alesund and better than 0.6...

Intercomparsion of O3 profiles observed by SCIAMACHY and ground based mircrowave instruments

Description : Ozone profiles retrieved from limb scattering measurements of the SCIAMACHY instrument based on the satellite ENVISAT are compared to ground based low altitutde resolution remote sensors. All profiles are retrieved using optimal estimation. Following the work of Rodgers and Connor (2003) the retriev...

Shipborne solar absorption measurements of CO2, CH4, N2O and CO and comparison with SCIAMACHY WFM-DOAS retrievals

Description : CO, CH4, N2O and CO2 were retrieved from high resolution solar absorption spectra obtained during a ship cruise from Capetown to Bremerhaven in January/February 2003 by Fourier Transform Infrared (FTIR) spectroscopy. Precisions of better than 0.5% for the column aver...

Seasonal and latitudinal variation of atmospheric methane: A ground-based and ship-borne solar IR spectroscopic study

Description : Column-averaged volume mixing ratios of CH4 were retrieved with a precision of better than 0.5% from infrared solar absorption spectra obtained at Ny-Alesund (Spitsbergen, 79°N) between 1997 and 2004 and during two ship cruises (54°N34°S) on the Atlantic in 2003. The retrieval has been performed in ...
