Data Sets from the Chemical Lagrangian Model of the Stratopshere (CLaMS)
Introduction
This data repository provides access to various data sets derived from simulations of the Chemical Lagrangian Model of the Stratopshere (CLaMS). The model CLaMS was developed in Jülich. Detailed information about the model CLaMS can be found on the CLaMS wiki pages here.
Example from one of the first CLaMS simulations and comparison with observations:
N2O mixing ratios simulated by CLaMS (left) and corresponding observations
by the CRISTA satellite experiment (right). Note the airmasses that originated from
the polar vortex marked with A and B.

Data access
Access is provided to data of the following studies:
Model Data Set for the study on the impact of dehydration on ozone loss
This data repository provides access to the model data of the study by Zhang-Liu et al. (2024). In this study, simulations of Antarctic chlorine and ozone chemistry in the core of the Antarctic vortex (16–18 km, 85–55 hPa, 390–430 K) are presented.
access
Model data set on rapid net HCl formation in the Antarctic spring
This data repository provides access to the model data of the study by Lehmann et al., submitted to the Journal of Atmospheric Chemistry (2021). In this study the rapid net HCl formation in the Antarctic spring stratosphere is examined.
access
Model data for the study on potential ozone loss in the mid-latitude lowermost stratosphere
This data repository provides access to results of the simulations conducted with the Chemical Lagrangian Model of the Stratosphere (CLaMS) for the study by Robrecht et al. (2021). This study is aimed to assess the potential of heterogeneous chlorine activation causing immense ozone destruction in the mid-latitude lowermost stratosphere in summer as a side effect of sulfate geoengineering.
access
Simulation of the record Arctic stratospheric ozone depletion in 2020
This data repository provides access to the model data of the study by Grooß and Müller submitted to JGR (2020). In this study, the unprecedented Arctic stratospheric ozone loss in the winter 2019/2020 is examined.
access
Wildfire smoke in the lower stratosphere identified by in situ CO observation
This data repository provides access to the trajectory data calculated for the study by Hooghiem et al. in Atmos Chem. Phys. (2020). In this study, wildfire-influenced airmasses were found in AirCore measurements over Sodankylä (Finland) that could be traced back to a wildfire in British Columbia (Canada) in August 2017.
access
Model data sets on HCl discrepancy
This data repository provides access to the model data of the study by Grooß et al. (2018). In this study, a discrepancy between model simulations and observations of HCl in the dark polar stratosphere is investigated.
access
Model Data Sets for the study on polar HCl depletion
This data repository provides access to the model data of the study by Grooß et al. (2025). In this study, a discrepancy between model simulations and observations of HCl in the dark polar stratosphere (see here) is further investigated.
