Tropical troposphere to stratosphere transport of carbon monoxide and long-lived trace species in the Chemical Lagrangian Model of the Stratosphere (CLaMS)
Tropical troposphere long-lived
2014/12/19
Variations in the mixing ratio of trace gases of tropospheric origin entering the stratosphere in the tropics are of interest for assessing both troposphere to stratosphere transport fluxes in the tro...

variational fl ux inversion system TOMCAT chemical transport model
2014/12/19
We present a new variational inverse transport
model, named INVICAT (v1.0), which is based on the global
chemical transport model TOMCAT, and a new corresponding adjoint transport model, ATOMCAT. Th...
Semi-Lagrangian transport of oxygen isotopes in polythermal ice sheets: implementation and first results
Semi-Lagrangian transport oxygen isotopes polythermal ice sheets implementation first results
2014/12/19
Modelling the evolution of the Earth system on long timescales requires the knowledge and understanding of driving mechanisms, such as the hydrological cycle. This is dominant in all components of the...
CranSLIK v1.0: stochastic prediction of oil spill transport and fate using approximation methods
stochastic prediction oil spill transport fate using approximation methods
2014/12/19
This paper investigates the development of a model, called CranSLIK, to predict the transport and transformations of a point mass oil spill via a stochastic approach. Initially the various effects on ...

2014/12/19
An ensemble Kalman filter (EnKF) assimilation method is applied to the tracer transport using the same stratospheric transport model as in the four-dimensional variational (4D-Var) assimilation system...
The implementation of the CLaMS Lagrangian transport core into the chemistry climate model EMAC 2.40.1: application on age of air and transport of long-lived trace species
chemistry climate model long-lived
2014/12/19
Lagrangian transport schemes have proven to be useful tools for modelling stratospheric trace gas transport since they are less diffusive than classical Eulerian schemes and therefore especially well ...
Regional scale ozone data assimilation using an ensemble Kalman filter and the CHIMERE chemical transport model
Regional scale ozone data ensemble Kalman fi lter
2014/12/18
An ensemble Kalman filter (EnKF) has been coupled to the CHIMERE chemical transport model in order to
assimilate ozone ground-based measurements on a regional
scale. The number of ensembles is...
