Description
The Ozone Monitoring Instrument (OMI) is a contribution of the
Netherlands's Agency for Aerospace Programs (NIVR) in
collaboration with the Finnish Meteorological Institute (FMI)
to the EOS Aura mission. It will continue the TOMS record for
total ozone and other atmospheric parameters related to ozone
chemistry and climate. OMI measurements will be highly
synergistic with the other instruments on the EOS Aura
platform. The OMI instrument employs hyper spectral imaging in
a push-broom mode to observe solar backscatter radiation in
the visible and ultraviolet. The Earth will be viewed in 740
wavelength bands along the satellite track with a swath large
enough to provide global coverage in 14 orbits (1 day). The
nominal 13 x 24 km spatial resolution can be zoomed to 13 x 13
km for detecting and tracking urban-scale pollution
sources. The hyper spectral capabilities will improve the
accuracy and precision of the total ozone amounts. The hyper
spectral capabilities will also allow for accurate radiometric
and wavelength self calibration over the long term. The
expanded wavelength characteristics will provide the following
features.

Continue global total ozone trends from satellite measurements
beginning in 1970 with BUV on Nimbus-4.

Map ozone profiles at 36 x 48 km, a spatial resolution never
achieved before.

Measure key air quality components such as NO2, SO2, BrO,
OClO, and aerosol characteristics.

Distinguish between aerosol types, such as smoke, dust, and
sulfates. Measure cloud pressure and coverage, which provide
data to derive tropospheric ozone.

Map global distribution and trends in UV-B radiation.

A combination of algorithms including TOMS version 7,
Differential Optical Absorption Spectroscopy (DOAS), Hyper
spectral BUV Retrievals and forward modeling will be used
together to extract the various OMI data products.

Near Real Time (NRT) production of ozone and other trace gases.
