Aura's instruments contain advanced technologies developed specifically for environmental studies. Each instrument provides unique and complementary capabilities that enable daily global observations of Earth's atmospheric ozone layer, air quality, and key climate parameters.

The four main intsruments on Aura are:

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

These instruments will provide valuable information about the ozone layer in the upper atmosphere and the quality of the air we breathe near the Earth's surface.
