CLEMENTINE LWIR BRIGHTNESS TEMPERATURE V1.0

This volume contains the archive of Lunar brightness temperature data derived from images acquired by the Clementine Long Wavelength Infrared (LWIR) camera. The LWIR camera acquired approximately 220,000 thermal-infrared images of the lunar surface that were used to generate the brightness temperature images within this archive. The procedure for generating brightness temperature values can be summarized as follows: 1) original LWIR digital numbers were converted to radiance; 2) the dark current signal was subtracted from the radiance values; 3) a flat field correction was applied; 4) bad pixels were identified and smoothed over; and 5) calibrated radiance values were converted to brightness temperatures using the Planck function.
