The proposed project aims to extend and improve the O3 and NO2 products of GOME. A new technique for the combined retrieval and assimilation of NO2 will be further developed and applied. A five-year data set of assimilated fields of O3 and NO2 based on GOME total column and profile observations will be generated. The global fields of O3 and NO2 will be made freely available to the scientific community. The data sets will be compared to independent observations obtained during measurement campaigns and from monitoring networks. These validation results will be made available as well. The data sets will be confronted with output from global chemistry-transport models to improve their modelling capability of current and future changes of ozone and chemically active greenhouse gases. The comparisons of model results with observations will also be used to specify requirements for measurements of chemical compounds for future chemical missions.
