Housed at the Cooperative Institute for Meteorological Satellite Studies (SSEC) at the University of Wisconsin - Madison, the atmospheric emitted radiance interferometer (AERI) "measures downwelling infrared radiation from 3-25 "m at less than one wavenumber resolution every ten minutes." Users can learn about the instrument's many applications including atmospheric profiling and cloud data collecting. The website features an informational slideshow about the instrument radiometric calibration. Researchers can view real-time and archived data and graphs on temperature, water vapor, and more for sites within United States such as Madison, Wisconsin and Lamont, Oklahoma.
