Analysis compares pump efficiency corrections for ozone profiles in Australia, indicating improved accuracy with Dütsch correction.
The Brewer-Mast (BM) ozonesonde has been used in Australia for measuring the profile of atmospheric ozone to above the middle stratosphere from the mid-1960s to 1990. An important experimental parameter in the interpretation of the measured ozone profiles is the pump efficiency correction. An analysis is presented here that tests two different pump corrections by comparison with SAGE II ozone satellite data. Results indicate that the Dütsch pump efficiency correction produces adjustments to these BM ozonesonde profiles that are in better quantitative agreement with the SAGE II satellite data.
