The heterogeneous photochemical reactions performed in this study demonstrate that ClONO2 adsorbed on ice crystals can be photolyzed by near-UV and visible light. The main photochemical products Cl2 and Cl2O are released into the gas phase and therefore can contribute directly or indirectly to ozone destruction.

Further experiments should be performed to get an insight into the mechanisms which are responsible for the products found in the heterogeneous photochemistry of ClONO2 adsorbed on ice crystals.
