Interactive comment on “ Two mechanisms of stratospheric ozone loss in the Northern hemisphere , studied using data assimilation of Odin / SMR atmospheric observations ” by Kazutoshi

General: The paper presents the analysis of stratospheric ozone loss in the Northern hemisphere during the period 2002-13 as derived from the DIAMOND model simulations which are assimilated to the Odin/SMR satellite observations. It compares the chlorineinduced with NOx-induced ozone loss and shows that the second effect is extremely important during the warm NH winters which are disturbed by the SSWs. This important contribution is well-written and is supported by well-performed figures. The paper should be acceptable after minor revision with some minor points listed below.
