The Chemical Lagrangian Model of the Stratosphere (CLaMS)

CLaMS (Chemical Lagrangian Model of the Stratosphere) is a modular chemistry transport model (CTM) system developed at Research Centre Jülich, Germany. CLaMS was first described by McKenna et al (2000a,b) and was expanded into three dimensions by Konopka et al (2004). CLaMS has been employed in various European aircraft field campaigns including THESEO, EUPLEX, TROCCINOX, SCOUT-O3, RECONCILE and STRATOCLIM with a focus on simulating ozone depletion and water vapour transport.

Major strengths of CLaMS in comparison to other CTMs are

its low diffusive Lagrangian transport scheme with the ability to reproduce small-scale structures and gradients of trace species
its applicability for reverse domain filling studies
its anisotropic mixing scheme
its integrability with arbitrary observational data
its comprehensive chemistry scheme

CLaMS-ice is a combination of CLaMS trajectories with the double moment bulk microphysics scheme cirrus_bulk for calculating cirrus formation.

CLaMS data sets

A chemical transport model does not simulate the dynamics of the atmosphere. For CLaMS, the following meteorological data sets have been used

European Centre for Medium-Range Weather Forecasts (ECMWF), Predictions, Analyses, ERA-15, ERA40, ERA-Interim
United Kingdom Meteorological Office (UKMO)
European Centre Hamburg Atmospheric Model (ECHAM4), in the DLR version

To initialize the chemical fields in CLaMS, a large variety of instruments have provided data

on satellite (CRISTA, MIPAS, MLS, HALOE, ILAS, MOPITT, AIRS, ...),
on aircraft and balloons (HALOX, FISH, Mark IV, BONBON, ...)
emission inventories (RETRO, EDGAR, GFED, ICE, ...)

If no observations are present, the chemical fields can be initialised from two-dimensional chemical models, chemistry-climate models, climatologies, or from correlations between chemical species or chemical species and dynamical variables.

Example animations

Example animations from a CLaMS simulation of the 2004/05 winter are shown on the page ExampleAnimations.
