definition: The Imaging Infrared Radiometer (IIR) instrument on CALIPSO is a three-channel IIR is provided by CNES with algorithm development performed by the Institute Pierre Simon Laplace (IPSL) in Paris. The IIR a nadir-viewing, non-scanning imager having a 64 km by 64 km swath with a pixel size of 1 km. The CALIOP beam is nominally aligned with the center of the IIR image. The instrument uses a single microbolometer detecter array, with a rotating filter wheel providing measurements at three channels in the thermal infrared window region at 8.7 mm, 10.5 mm, and 12.0 mm. These wavelengths were selected to optimize joint CALIOP/IIR retrievals of cirrus cloud emissivity and particle size.
