The continental source of glyoxal estimated by the synergistic use of spaceborne measurements and inverse modelling
glyoxal spaceborne measurements inverse modelling
2009/11/19
Tropospheric glyoxal and formaldehyde columns retrieved from the SCIAMACHY satellite instrument in 2005 are used with the IMAGESv2 global chemistry-transport model and its adjoint in a two-compound in...
Inverse modelling of atmospheric tracers:non-Gaussian methods and second-order sensitivity analysis
Inverse modelling atmospheric tracers non-Gaussian methods second-order sensitivity analysis
2009/10/30
For a start, recent techniques devoted to the reconstruction of sources of an atmospheric tracer at continental scale are introduced. A first method is based on the principle of maximum entropy on the...
Concentration Data and Dimensionality in Groundwater Models:Evaluation Using Inverse Modelling
Concentration Data Groundwater Models Inverse Modelling
2009/10/23
A three-dimensional inverse groundwater flow and transport model that fits hydraulic-
head and concentration data simultaneously using nonlinear regression
is presented and applied to a layered sand...
Inverse modelling in estimating soil hydraulic functions: a Genetic Algorithm approach
Genetic Algorithm inverse modelling
2009/3/17
The practical application of simulation models in the field is sometimes hindered by the difficulty of deriving the soil hydraulic properties of the study area. The procedure so-called inverse modelli...
Mass balance inverse modelling of methane in the 1990s using a Chemistry Transport Model
Mass balance inverse modelling Chemistry Transport Model
2009/3/10
A mass balance inverse modelling procedure is applied with a time-dependent methane concentration boundary condition and a chemical transport model to relate observed changes in the surface distributi...
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 fate and transport of mercury over Europe is studied using a regional Eulerian transport model. Because gaseous elemental mercury is a long-lived species in the atmosphere, boundary conditions mus...
Inverse modelling of the spatial distribution of NOx emissions on a continental scale using satellite data
spatial distribution of NOx emissions continental scale satellite data
2009/1/8
The recent important developments in satellite measurements of the composition of the lower atmosphere open the challenging perspective to use such measurements as independent information on sources a...
Inverse modelling-based reconstruction of the Chernobyl source term available for long-range transport
Chernobyl source long-range transport
2008/12/4
The reconstruction of the Chernobyl accident source term has been previously carried out using core inventories, but also back and forth confrontations between model simulations and activity concentra...
Four-dimensional variational data assimilation for inverse modelling of atmospheric methane emissions: method and comparison with synthesis inversion
Four-dimensional variational data atmospheric methane synthesis inversion
2008/11/25
A four-dimensional variational (4D-Var) data assimilation system for inverse modelling of atmospheric methane emissions is presented. The system is based on the TM5 atmospheric transport model. It can...
We give here an account on the results of source inversion of the ETEX-II experiment. Inversion has been performed with the maximum entropy method on the basis of non-zero measurements and in conjunct...
