TL;DR: In this article, a global Bayesian variational inversion of CO2 surface fluxes during the period 1988-2008 is presented, where weekly fluxes are estimated on a 3.75 degrees x 2.5 degrees (longitude-latitude) grid throughout the 21 years.
Journal ArticleDOI

TL;DR: The TransCom continuous experiment as mentioned in this paper was designed to evaluate the performance of forward transport model simulations at hourly, daily, and synoptic timescales, and focus on the latter two in this paper.
Journal ArticleDOI
Dry deposition of reactive nitrogen to European ecosystems: a comparison of inferential models across the NitroEurope network
Christophe Flechard,Eiko Nemitz,Ron Smith,David Fowler,Alex Vermeulen,Albert Bleeker,Jan Willem Erisman,David Simpson,David Simpson,Leiming Zhang,Y.S. Tang,Mark A. Sutton +11 more
TL;DR: In this article, an inferential network of 55 sites throughout Europe for atmospheric reactive nitrogen (N-r) was established in 2007, providing ambient concentrations of gaseous NH3, NO2, HNO3 and HONO and aerosol NH4+ and NO3- as part of the NitroEurope Integrated Project.

TL;DR: In this paper, an estimate of net ecosystem exchange (NEE) of CO2 in Europe for the years 2001-2007 is presented with a data assimilation that uses a large set of atmospheric CO2 mole fraction observations (∼70 000) to guide relatively simple descriptions of terrestrial and oceanic net exchange, while fossil fuel and fire emissions are prescribed.
Journal ArticleDOI
Inverse modelling of national and European CH4 emissions using the atmospheric zoom model TM5
Peter Bergamaschi,Maarten Krol,Frank Dentener,Alex Vermeulen,Frank Meinhardt,R. Graul,M. Ramonet,Wouter Peters,Edward J. Dlugokencky +8 more
TL;DR: In this paper, a synthesis inversion based on the atmospheric zoom model TM5 is used to derive top-down estimates of CH 4 emissions from individual European countries for the year 2001.
