(author)European CH4 and N2O emissions are estimated for 2006 and 2007 using four inverse modelling systems, based on different global and regional Eulerian and Lagrangian transport models. This ensemble approach is designed to provide more realistic estimates of the overall uncertainties in the derived emissions, which is particularly important for...article 2015

(author), Bousquet, P. (author)This study examines N2O emission estimates from five different atmospheric inversion frameworks based on chemistry transport models (CTMs). The five frameworks differ in the choice of CTM, meteorological data, prior uncertainties and inversion method but use the same prior emissions and observation data set. The posterior modelled atmospheric...article 2014

(author), Forster, G. (author), Sturges, W.T. (author)This work reassesses the global atmospheric budget of H2 with the TM5 model. The recent adjustment of the calibration scale for H2 translates into a change in the tropospheric burden. Furthermore, the ECMWF Reanalysis-Interim (ERA-Interim) data from the European Centre for Medium-Range Weather Forecasts (ECMWF) used in this study show slower...article 2013

(author), Forster, G. (author), Sturges, W.T. (author)Since the industrialisation of fuel cell technology during the 1970s and 80s, molecu3 3 lar hydrogen (H2) has been considered as a clean alternative for fossil fuel based energy 34 carriers. The selective oxidation of H2 by oxygen only produces water, contrary to the 35 combustion of fossil fuels with air that produces carbon dioxide, carbon...article 2012

(author), Energieonderzoek Centrum Nederland (author)Atmospheric measurements combined with inverse atmospheric models can provide independent top-down estimates of greenhouse gas (GHG) emissions. This is important in particular for N2O and CH4, for which considerable uncertainties of the bottom-up inventories exist (uncertainty estimates of bottom-up emissions reported to UNFCCC: CH4: 30%; N2O ...conference paper 2011
