Jan-2004
| Aura (formerly EOS/Chem-1) is the chemistry mission of NASA with the overall
objective to study the chemistry and dynamics of Earth’s atmosphere from the
ground through the mesosphere. The Ozone Monitoring Instrument (OMI) is a nadir-viewing UV/VIS imaging
spectrograph that measures the solar radiation backscattered by the Earth’s
atmosphere and surface over the entire wavelength range from 270 to 500 nm,
with a spectral resolution of about 0.5 nm. The design is of GOME heritage, flown
on ERS-2, as well as of SCIAMACHY and GOMOS heritage, flown on Envisat. Read more
