Aura Mission

Objectives and Applications

6-year nominal mission life, currently in extended operations. Measurements of aerosol and cloud properties for climate predictions, using a 3-channel lidar and passive instruments in formation with CloudSat for coincident observations of radiative fluxes and atmospheric state.

AURA
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
