Atmospheric Emitted Radiance Interferometer (AERI)

Principle

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. Spectral observations from 612-713 1/cm and 2223-2260 1/cm (i.e., measurements from the 15 µm and 4.3 µm CO2 bands, respectively) have been used for temperature profiling, and observations from 538-588 1/cm and 1250-1350 1/cm (i.e., measurements from the wings of the rotational and 6.3 µm water vapor bands, respectively) for water vapor profiling. Additionally selected window channels provide information on ice cloud, as well as low-LWP (< 50 g/m2) liquid water cloud effective radius and cloud optical depth.
