- | The AERI is an operational infrared spectrometer that measures the downwelling infrared radiance from 3.3-19 µm (3020 to 520 1/cm) at 1/cm resolution. The AERI has approximately 2500 spectral channels for each of its two detectors. Like the microwave spectrum, the infrared spectrum also contains information on the vertical profile of temperature and humidity.
