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.
