Model Data Set for the study on the impact of dehydration on ozone loss

Introduction

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. Under these conditions, HCl null cycles are effective. These HCl null cycles cause HCl molar mixing ratios to remain very low throughout Antarctic winter/spring and ozone destroying chlorine to remain enhanced, so that rapid ozone depletion proceeds. Here access to the results of the box-model simulations presented and discussed in the publication is provided. All simulations for the core of the Antarctic vortex show extremely low minimum ozone values (below 50 ppbv) in late September/early October in agreement with observations.

Data access

The data sets provided on this web site are saved for the box model simulations using CLaMS. For a model description and all other details, we refer to Zhang-Liu et al. (2024). The file format is NetCDF that is described here. Note that these files are non-operational research data products, which have been made available to other scientists and the general public. Simulations S1 to S4 are defined in Table 2 and simulation multi_S2 is descibed in section 3.4 of Zhang-Liu et al. (2024).
