For the OMI-EOS instrument on EOS-Aura, Finnish industry, led by the Finnish Meteorological Institute (FMI), has provided the
Electronics Unit as well as the Detector Modules. In the operational phase of the mission, FMI will conduct its research on
OMI data in close collaboration with KNMI, NASA and other members of the International OMI Science Team. The specific
contributions from Finland are the UV product, with heritage from the TOMS UV product, the Direct Broadcast receiving and
processing to Very Fast Delivery products in Sodankyl\"{a} (68 degrees North, 25 degrees East) as well as combining the OMI
data with GOMOS data from ENVISAT, OSIRIS from Odin spacecraft, and active participation in the OMI validation programme.
The FMI science team has participated in the improvement of the TOMS UV product at high latitudes in collaboration with
NASA/GSFC. The most important contribution is a new surface albedo climatology to be used in generating the OMI UV product.
In addition, input sanity check and quality flagging routines have been implemented in the UV algorithm. In addition to
providing an improved algorithm for UV processing, FMI will also process and archive the global UV product during the Aura
mission.
The Arctic Research Centre of FMI has launched ozone-sounding balloons since 1988, and developed research infrastructure for
supporting validation campaigns. Earlier campaigns have included ozone soundings, water vapour soundings, aerosol soundings
and column ozone measurements from Brewer and SAOZ spectrometers. These facilities will be used in Aura validation, with
special emphasis on validating the FMI-generated OMI UV product with ground data and comparisons with TOMS UV product.
The FMI Team is also active in two profiling instruments: GOMOS and OSIRIS. After the launch of OMI we have a unique
opportunity to combine OMI total column data with the profile information obtained from those missions. Assimilation methods
are being developed to join those data for research use. In this presentation we discuss the elements and readiness of the
FMI programme.
