Abstract

In this paper the OMI ozone column measurements obtained with the TOMS-V8 total ozone algorithm are evaluated against OMI ozone columns simulated by means of ozone analyses resulting from assimilation of standard meteorological observations as well as independent ozone retrievals into a numerical weather prediction model. Intercomparison results between measured versus simulated OMI ozone columns at sza < 70 deg show a relative bias of -3.2±3.1% and an RMSE of 4.5±1.5%. The resulting bias is consistent with current estimates of the bias of OMTO3 columns with respect to SBUV/2 over the -60 deg +60 latitude band.
