Hirata, Absolute calibration of brightness temperature of the Venus disk observed by the Longwave Infrared Camera onboard Akatsuki, Earth, Planets and Space, 69, 141, 2017 This paper contains LIR calibration scheme. Longwave Infrared Camera Imager Bolometer -5500 The Longwave Infrared Camera (LIR) detects thermal emission from the cloud top over a rather wide wavelength region of 8-12 um in order to map the cloud-top temperature. Unlike the other imagers onboard Akatsuki spacecraft, LIR is able to take both dayside and nightside images with equal quality and accuracy. The cloud-top temperature map will reflect the cloud height distribution, the detailed structure of which remains unknown, except in the high latitude observed by the Pioneer Venus, as well as the atmospheric temperature distribution.
