The Atmospheric Emitted Radiance Interferometer, or AERI™, is a ruggedized automated sounding spectroradiometer system based on more than 20 years of field experience. Now in its 4th generation, AERI instruments incorporate the newest generation of ABB’s FT-IR spectroradiometer (the field proven MR-300 series), University of Wisconsin blackbody cavity, latest COTS signal conditioning units, and new detector/Stirling cooler (ITAR-free) with extended lifetime.

It measures absolute down-welling atmospheric emitted infrared radiance with high accuracy. This remote sensing tool can work year-round during both day and night (except during precipitation), continuously providing temperature and humidity profiles unattended every 8 minutes.

AERI technology development through successive design generations is the result of 20 years of heritage at ABB.
