A second application of this product is its use in data assimilation of the global ozone distribution. Assimilated ozone field which are timely available can be published on the Internet to inform public, scientist and decision makers on the current status of the ozone layer and the tropospheric ozone. An important requirement derived from this application is a reliable error-estimation. Further target applications of height resolved ozone are the monitoring of the ozone layer and the use of ozone information in UV forecasts. Ozone profiles shall be calculated for all GOME channel 1a spectra.
Global coverage is reached every three days.
The size of the ground pixel for channel 1a is 960x100 km 2 . The profile retrieval requires the channel 1a, 1b and channel 2 data of the level 1b product. The sources of error that influence the quality of the Level 2 ozone-profile product can be arranged into three factors. The accuracy of the ozone profile depends critically on the properties and the quality of the level 1b spectra. The error on the wavelengths.
