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...
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...
Improving the representation of secondary organic aerosol (SOA) in the MOZART-4 global chemical transport model
secondary organic aerosol MOZART-4
2014/12/12
The secondary organic aerosol (SOA) module
in the Model for Ozone and Related Chemical Tracers,
version 4 (MOZART-4) was updated by replacing existing two-product (2p) parameters with those obtained...
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...
Observation operator for the assimilation of aerosol type resolving satellite measurements into a chemical transport model
aerosol type satellite measurements a chemical transport model
2010/11/29
Modelling of aerosol particles with chemical transport models is still based mainly on static emission databases while episodic emissions cannot be treated sufficiently. To overcome this situation, a ...
A general parallelization approach to improve computation efficiency in a global chemical transport model (GEOS-Chem)
MPI OpenMP parallelization GEOS-Chem modeling performance
2017/8/9
Despite increasing processing power of systems, sequential programs have limitations to achieve corresponding performance gains. Parallelization of sequential programs can exploit the computation pote...
Estimated total emissions of trace gases from the Canberra Wildfires of 2003: a new method using satellite measurements of aerosol optical depth & the MOZART chemical transport model
