It is designed to make a systematic study of the stratosphere and provide new data on the mesosphere and thermosphere. The satellite was launched on 12th September 1991. The project scientist is Dr Mark Schoerberl at NASA Goddard. Parameters measured by the various chemistry and dynamics instruments are shown in a Parameters Table . The combination of orbit and instrument design provides nearly global coverage.
Plots showing the latitudinal coverage and the vertical coverage of the instruments are available.
Four instruments measure chemical composition. Level 3A also holds the correlative analyses which were produced by the UK Met. Office as their contribution to the UARS project. The UARS L3A file name convention is also available. UARS Plots The Goddard UARS project office keeps an archive to which investigators can submit copies of interesting or useful plots.
