CRISM Spectral Library

The CRISM Spectral Library is a collection of laboratory spectra of Mars-analog materials supplied by the CRISM Team. The spectra will be used to compare with spectra acquired by CRISM.

More information about CRISM is available on the CRISM web site at APL.

Spectral Library Interface

August 30, 2012: The old web interface to the CRISM Spectral Library has been replaced by the new PDS Geosciences Spectral Library service, which incorporates the data from the CRISM Spectral Library as well as data from other contributors. The tool allows search, display and download of spectra based on the material classification and other parameters. 

Online Data

The CRISM Spectral Library is stored as a standard PDS archive volume that may be accessed by web or FTP (see below).
