AB: The comprehensive intercomparison of SBUV/SBUV2 (Solar Backscatter Ultra-Violet) and Umkehr total and profile ozone data is presented. This paper discusses consistency between the two datasets. The recently updated retrieval algorithms for both systems are verified through the use of radiative transfer code. The SBUV data records from Nimbus-7, NOAA-9, NOAA-11, and NOAA-16 satellites covering period from November 1978 through December 2003 have been reprocessed by NOAA-NASA ozone team using newly-developed Version 8 retrieval algorithm. Umkehr data selected for comparisons include ozone measurements taken at Tateno (Japan), Arosa (Switzerland), and Boulder (USA) Dobson stations. Umkehr retrieval algorithm was recently updated at NOAA/SRRB. We have compared monthly-averaged total column and profile ozone obtained from the set of coincident (within place and time) observations. Using TOMRAD radiative transfer code we have simulated SBUV measurement signal from Umkehr and SBUV coincident profiles to assess compatibility of forward model and inversion algorithms for both instruments. Measurement residuals and their possible causes obtained during these simulations are discussed.
