MRO: CRISM
|
September 23, 2024. The MRO CRISM
MTRDRs have 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 archive. The
original data files are unchanged. Please see
readme.txt for more
information. |
CRISM is the Compact Reconnaissance Imaging
Spectrometer for Mars, a visible-infrared hyperspectral
mapper that maps the geology, composition, and layering
of surface features on Mars. CRISM data sets are produced by
the CRISM Science Team at Johns Hopkins University
Applied Physics Laboratory, Laurel, Maryland.
NOTE: CRISM L data stopped being
collected on February 15, 2018, due to
failure of the thermoelectric coolers.
CRISM Documentation
Read the
CRISM Data Product Specification,
also known as the CRISM SIS (PDF, 9 MB) for information about the structure and content of CRISM
data products. This is essential reading for
any CRISM user. Additional help in
processing and using CRISM data is available in the
presentations from the
MRO CRISM Data Users' Workshop.
The various CRISM observing modes are described in
the poster
The
Illustrated Guide to CRISM Observing Modes
(May 2017) and in this presentation from the CRISM Team,
Brief
History of CRISM Observing Modes
(November 2015).
Read the
CRISM
Data Set Specification (PDF, 1.5 MB) for information
about the organization of CRISM data sets. There is more than just the data products!

Note Regarding TRDR Version 3
Reprocessing
As of February 9, 2010,
the
TRDRs (Targeted Reduced Data
Records) are being created with version 3 of the CRISM processing
software, which includes improved calibration
procedures. Compared to version 2 TRDRs, these
products have had most artifacts corrected and
noise reduced by use of a sophisticated filtering
process. The CRISM Team
has revised all previously released TRDRs using the
improved software. For more information see the
revised Data Set Description (trdr_ds.cat) and
Software Interface Specification (crism_dpsis.pdf).
The previously released TRDR
version 2 products have been taken offline.
CDRs (Calibration Data Records)
have also been reprocessed as part of this
effort. The Version 3 CDRs are stored on the EDR volumes in their usual
CDR directory, and the Version 2 CDRs that they
replace have been taken
offline.
Users of TRDR Version 3 products please note: The
hyperspectral noise filter applied to the I/F version
of CRISM TRDRs in version 3 of the radiometric
calibration pipeline is described in
this file (PDF,
13.3 MB). The format of the file is a
flowchart describing different steps in the filtering
process, which is applied to full or half resolution
targeted observations (the central swaths of FRT, HRL,
or HRS observations). Other products taken with
greater levels of pixel binning are not filtered at
this time. A future version of the CRISM Data Products
SIS will describe the filtering algorithm in greater
detail.
