Abstract We adopt our GOME ozone profile and
tropospheric column ozone algorithm to both
operational and recent verification (with a
15-20 correction in irradiance) SCIAMACHY data
(290-310 and 325-339 nm). The retrieval
performance is better for the original SCIAMACHY
data, although a large systematic bias exists.
The verification correction corrects much of the
systematic bias, but it may introduce additional
structures that degrade the retrievals. The
preliminarily retrievals of 3 orbits of data
(from the original SCIAMACH data) agree well with
KNMI TOSOMI data to within 3.86.8 DU (1.12.1,
R0.993) and agree with SAGE-II ozone profiles (2
coincidences) to within 15 down to 20 km. More
comparisons with ozonesonde, SAGE, and
Dobson/Brewer data are necessary to validate and
improve the retrievals.
