Mars Global Surveyor:
MOLA
The Mars Orbiter Laser
Altimeter (MOLA) generates altimetry profiles that are
used to create global topographic maps. The MOLA
instrument stopped acquiring altimetry data on June 30,
2001, and since then has operated in passive radiometry
mode. MOLA data sets are produced by the MOLA Science
Team and archived by the PDS Geosciences Node.
April 27, 2007 The final delivery
of MOLA radiometry data
is now online.
MOLA Products and IAU
Coordinates
The final version
(Version L) of the MOLA PEDR data set was generated
using the IAU 2000 coordinate system. The final version
of the MOLA topographic maps (MEGDRs) was generated from
the Version L PEDRs, and therefore also uses the IAU
2000 coordinate system. Older versions of MOLA PEDRs and
topographic maps were created in the IAU 1991 system.
For more information, see the
PEDR Data Set Information under Data Set
Overview.
MOLA Data Distribution
Schedule
MOLA data were delivered to the PDS
every three months while the altimeter was still
collecting data. Since June 30, 2001, MOLA has been used
as a passive radiometer. The archive of radiometry data
has passed a PDS peer review.
