| 500 | _ | _ | |a The authors thank Rolf Muller for very fruitful discussions and three anonymous reviewers for comments that resulted in significant improvements to the original manuscript. The study was funded by the European Commission as part of the project "A European Network for Atmospheric Hydrogen observations and studies (EUROHYDROS)" under contract 036916. Simulations were performed on the Julich Multiprocessor (JUMP) and were supported by the John von Neumann Institute for Computing (NIC). |
| 520 | _ | _ | |a Possible causes of a future increase in stratospheric H2O are increasing tropospheric methane levels and a rise in tropospheric H-2 due to leakages from a possible increased integration of hydrogen into the energy supply system. Here we quantify the direct chemical impact of potential future stratospheric H2O increases on Arctic ozone loss using the cold Arctic winter 2004/2005 as the basis for our study. We present simulations with the three-dimensional chemistry transport model CLaMS using enhanced stratospheric H2O values. Previous studies emphasized that increasing H2O concentrations cause stratospheric cooling, and some have suggested that this could significantly increase halogen-induced polar ozone loss. The impact of both increased stratospheric H2O values and decreased temperatures on simulated ozone depletion is investigated. Assuming an average increase of water vapor in the lower polar stratosphere of approximate to 0.58 ppmv (averaged over equivalent latitudes >= 65 degrees N, from 400-550 K potential temperature and from December to March) and in addition decreased temperatures (-0.2 K) yields at most 6.8 DU (approximate to 11 %) more accumulated ozone loss in mid-March for the Arctic polar winter 2004/2005 compared to the ozone loss for undisturbed conditions. The assumed H2O enhancement in future decades is in the range of current model predictions. Considering in addition the decrease of the future chlorine loading (-40 %) of enhanced H2O values (see above) yields at most 3.4 DU (10 %) of accumulated ozone loss in springtime compared to current H2O values. The impact of a potential future hydrogen economy alone (assuming an averaged increase of 0.18 ppmv H2O in the lower stratosphere) on springtime accumulated ozone loss is found to be negligible (at most 2.5 DU (4 %)) in this study. |
