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 N–34 S) on the Atlantic in 2003. The retrieval has been
performed in...

Description :
We present long-term time-series of strato-mesospheric CO vertical columns measured from stations located in Antarctica, mid-latitudes and the Arctic, covering the period from 1997?2005. The instrument and the measurement technique allows the separation of tropospheric and strato-mesospheric contrib...

Description :
This paper describes the statistical analysis of annual trends in long term datasets of greenhouse gas measurements taken over ten or more years. The analysis technique employs a bootstrap resampling method to determine both the long-term and intra-annual variability of the datasets, together with t...

Description :
Carbon monoxide total column amounts in the atmosphere have been measured in the High Northern Hemisphere (30°-90° N, HNH) between January 2002 and December 2003 using infrared spectrometers of high and moderate resolution and the Sun as a light source. They were compared to ground-level CO mixing r...
