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...
Development of a variational flux inversion system (INVICAT v1.0) using the TOMCAT chemical transport model
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...
Comparing microbial and chemical kinetics for modelling soil organic carbon decomposition using the DecoChem v1.0 and DecoBio v1.0 models
Comparing microbial chemical kinetics modelling soil organic carbon decomposition DecoChem v1.0 DecoBio v1.0 models
2014/12/19
Soil organic matter is a vast store of carbon, with a critical role in the global carbon cycle. Despite its importance, the dynamics of soil organic carbon decomposition, under the impact of climate c...
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...
Turbulent transport, emissions and the role of compensating errors in chemical transport models
Turbulent transport emissions
2014/12/18
The balance between turbulent transport and emissions is a key issue in understanding the formation of O3 and
particulate matter with diameters less than 2.5 μm (PM2.5)Discrepancies between observed ...
Identifying the causes of differences in ozone production from the CB05 and CBMIV chemical mechanisms
ozone production CB05
2014/12/11
An investigation was conducted to identify the
mechanistic differences between two versions of the carbon
bond gas-phase chemical mechanism (CB05 and CBMIV)
which consistently lead to larger ground...
We present here the global chemical transport model Oslo CTM3, an update of the Oslo CTM2. The update comprises a faster transport scheme, an improved wet scavenging scheme for large scale rain, updat...

2014/12/10
A procedure for tagging ozone produced from NO sources through updates to an existing chemical mechanism is described, and results from its implementation in the Model for Ozone and Related chemical T...
Construction of non-diagonal background error covariance matrices for global chemical data assimilation
Chemical data assimilation To optimize the noise Model predictions Chemical state
2014/12/9
Chemical data assimilation attempts to optimally use noisy observations along with imperfect model predictions to produce a better estimate of the chemical state of the atmosphere. It is widely accept...
