The AERI was designed by the University of Wisconsin Space Science and Engineering Center (UW-SSEC) for the Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program in the 1990s.  The AERI instrument played an essential role in the success of the ARM program by providing an accurate reference in tropical, mid-latitude continental, and arctic atmospheres for the validation of infrared radiative transfer models used in climate models.  AERI instruments have since been deployed worldwide.  Long-term AERI data records are available at the DOE ARM fixed sites at the Southern Great Plains (SGP, 1995–present), the North Slope of Alaska (NSA, 1998–present), and the Tropical Western Pacific (1998–2014).  The AERIs in the ARM Mobile Facilities (AMF) have been deployed for field campaigns throughout the world.  The AMF-2 contains a Marine-AERI that is capable of shipboard deployment and can also measure sea surface emissivity and skin temperature.

The AERI technology has been licensed by the University of Wisconsin to the commercial company ABB Inc., who is currently responsible for the manufacture of the hardware and installation of the operating software.
