Validation of GOME total ozone column with the assimilation model KNMI
No full textThe two-dimensional global Assimilation Model KNMI (AMK) is used to validate GOME total ozone columns. A method is developed to derive an upper limit on the intrinsic (random) uncertainty in the GOME ozone values which makes use of the information carried in the model by a reliability flag. It is found that the intrinsic (random) uncertainty in GOME total ozone columns is rather small: less than 7 DU (or about 2%). Furthermore, a systematic error is identified which depends on the viewing directio
