Clementine LWIR Brightness Temperature Images

This archive contains 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. A complete description of the online volume structure and the image file format is in the file VOLSIS.TXT in the DOCUMENT directory. The Clementine LWIR brightness temperature data set was produced by Dr. Stefanie L. Lawson, Los Alamos National Laboratory, Los Alamos, New Mexico and Dr. Bruce M. Jakosky, University of Colorado, Boulder, Colorado.

These images have attached PDS labels and can be displayed with the PDS software NASAView.

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. Details of the processing are given in Lawson et al. (Journal of Geophysical Research, v. 105, pp. 4273-4290, 2000).
