Clementine LWIR
Brightness Temperature Images
|
September 8, 2023.
The Clementine LWIR
brightness temperature dataset has
been migrated to the PDS4 standard.
The original PDS3 data products,
labels, and documentation remain
available in their original archive
volume. The only change is that PDS4
labels and documentation have been
added to the archives. The original
data files are unchanged. Please see
the
pds4_migration_notes
for more information.

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 now have detached PDS4
labels (*.xml) and the original attached PDS3 labels.
They can be displayed with the
PDS4 Viewer tool and 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).
