We will analyze MIPAS high spectral resolution data with respect to heavy ozone isotopologues in order to obtain a global stratospheric dataset of ozone isotope composition. This data record will be examined whether hitherto unstudied processes like ozone UV photolysis or chemical decomposition have an effect on ozone isotopic composition in the stratosphere.
