EOS-Chem 1 (Aura)

EOS-Chem 1 (Aura) [Northrop Grumman]

The Aura (formerly EOS Chemistry-1) satellite will focus on measurements of atmospheric trace gases and their transformations. The objective of the mission is to study the chemistry and dynamics of the Earth's atmosphere from the ground through the mesosphere.

The Aura spacecraft will feature following instruments:

  • HIRDLS - High Resolution Dynamics Limb Sounder
  • MLS - Microwave Limb Sounder
  • OMI - Ozone Monitoring Instrument
  • TES - Tropospheric Emission Spectrometer

Originally it was planned to build three satellites to be launched in five year intervals, but only the first one was implemented.
