Atmospheric Emitted Radiance Interferometer - AERI (02). AERI. "The Atmospheric Emitted Radiance Interferometer (AERI) is a ground-based instrument that measures the downwelling infrared radiance (radiant energy) from the Earth’s atmosphere. The observations have broad spectral content, and sufficient spectral resolution to discriminate among gaseous emitters (e.g. carbon dioxide, water vapor) and suspended matter (e.g. aerosols, water droplets, ice crystals). These uplooking surface observations can be used to obtain vertical profiles of tropospheric temperature and water vapor, as well as measurements of trace gases (e.g. ozone, carbon monoxide, methane) and downwelling infrared spectral signatures of clouds and aerosols. " AERI observations are often used to validate and calibrate satellite observations. (Text from http://www.ssec.wisc.edu/aeri/). “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.” AERI observations are often used to validate and calibrate satellite observations. (Text from http://www.ssec.wisc.edu/aeri/history.html).
