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 recent European field campaigns THESEO, EUPLEX, TROCCINOX and SCOUT-O3 with a focus on simulating ozone depletion and water vapour transport.
Major strengths of CLaMS in comparison to other CTMs are
- its applicability for reverse domain filling studies
- its anisotropic mixing scheme
- its integrability with arbitrary observational data
- its comprehensive chemistry scheme

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
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, ...),
- on aircraft and balloons (HALOX, FISH, Mark IV, BONBON...)
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.
