Viking Orbiter
IRTM
Data from the Infrared Thermal Mapper
(IRTM) experiment on the Viking Orbiters is archived at
the PDS Geosciences Node.
This is one of the earliest data sets archived in
PDS. At the time (1989) the data formats and standards
now in use by PDS were not fully in place, so this
archive is not as complete or as accessible as
later archives.
The Viking IRTM data have been archived twice in PDS:
the first time in 1989 with the format and software that
were then in use by the data provider, and again in 1994
using a revised format and software that were intended
to be compatible with the TES data format (the Thermal
Emission Spectrometer on Mars Global Surveyor). Both
versions of the IRTM data are provided here.
Use the links below for direct access to any part of
the two archives. Or use
this link for FTP access to the archives. (FTP
users, read our
FTP instructions first.)

IRTM Version 2 (1994)
August 8, 2012
A user discovered that the file IRTM_ENVS
mentioned in the CIRTM documentation is
missing from the CIRTM tar file in the
Version 2 archive. The file has been
recovered and placed in the DOC directories
of VO_0001 and VO_0002, version 2.
Here's the link to
IRTM_ENVS.
