Inverse modeling of European CH4 emissions: sensitivity to the observational network
European CH4 emissions observational network
2010/2/21
Inverse modeling is widely employed to provide "top-down" emission estimates using atmospheric measurements. Here, we analyze the dependence of derived CH4 emissions on the sampling frequency and dens...
Multi-species inversion of CH4, CO and H2 emissions from surface measurements
Multi-species CH4 CO H2 emissions surface measurements
2009/8/7
In order to study the spatial and temporal variations of the emissions of greenhouse gases and of their precursors, we developed a data assimilation system and applied it to infer emissions of CH4, CO...
Technical note: A stratospheric climatology for O3, H2O, CH4, NOx, HCl and HF derived from HALOE measurements
stratospheric climatology O3 HF HALOE measurements
2009/2/18
The Halogen Occultation Experiment (HALOE) on board the Upper Atmosphere Research Satellite (UARS) has observed mixing ratios of important trace species in the stratosphere for more than a decade sinc...
Inverse modelling of national and European CH4 emissions using the atmospheric zoom model TM5
national and European CH4 emissions atmospheric zoom model TM5
2009/2/17
A synthesis inversion based on the atmospheric zoom model TM5 is used to derive top-down estimates of CH4 emissions from individual European countries for the year 2001. We employ a model zoom over Eu...
The impact of SCIAMACHY near-infrared instrument calibration on CH4 and CO total columns
SCIAMACHY near-infrared instrument calibration CH4 CO total columns
2009/2/17
The near-infrared spectra measured with the SCIAMACHY instrument on board the ENVISAT satellite suffer from several instrument calibration problems. The effects of three important instrument calibrati...
Comparisons between SCIAMACHY and ground-based FTIR data for total columns of CO, CH4, CO2 and N2O
SCIAMACHY ground-based FTIR data CO CH4 CO2 N2O
2009/1/8
Total column amounts of CO, CH4, CO2 and N2O retrieved from SCIAMACHY nadir observations in its near-infrared channels have been compared to data from a ground-based quasi-global network of Fourier-tr...
Simultaneous ground-based observations of O3, HCl, N2O, and CH4 over Toronto, Canada by three Fourier transform spectrometers with different resolutions
Simultaneous ground-based observations O3 HCl N2O CH4 three Fourier transform spectrometers
2008/12/3
An intercomparison of three Fourier transform spectrometers (FTSs) with significantly different resolutions is presented. The highest-resolution instrument has a maximum optical path difference of 250...
