Fig. 1From: Utilization of a meteorological satellite as a space telescope: the lunar mid-infrared spectrum as seen by Himawari-8(Upper) The AHI’s nine spectral passbands in mid-infrared wavelength. The red lines are the normalized response functions of bands 8–16 of AHI. The gray line is the atmospheric transmission calculated by ATRAN (Lord (1992); https://atran.arc.nasa.gov/cgi-bin/atran/atran.cgi). The blue and green shades correspond to wavelengths of water emission and Christiansen feature, respectively. (Lower) Comparison with other instruments onboard planetary exploration missions. The white and black bars are the response ranges of imagers and spectrometers on interplanetary spacecraft. The red shades and numbers are the AHI coverages and corresponding band namesBack to article page
