Ozone profile retrieval with OMI
Abstract
In January 2004 the Ozone Monitoring Instrument (OMI) will be launched. The main aim of the OMI mission is to monitor the ozone layer for the next 5 years. Both total column amounts and the vertical distribution of ozone will be retrieved and used for this purpose. In this poster we provide an overview of the algorithm that will be used to retrieve the vertical distribution of ozone: the ozone profile. We emphasize the need for taking into account the effects of polarisation on the transfer of the backscattered radiation through the atmosphere. We present results of retrievals using this algorithm for Global Ozone Monitoring Experiment (GOME) data for the full year 2000. We also show comparisons with collocated ground measurements with the purpose of quantifying the capacity of GOME and OMI to deliver height resolved information on ozone and to establish the accuracy of the product. The OMI ozone profile algorithm differs to some degree from the operational GOME algorithm. We discuss the origin and the implementation of these differences.
