MRO CRISM VNIR HYPERSPECTRAL REDUCED DATA RECORD V1.0
Listed in NASA Data Portal
This dataset contains CRISM VNIR Hyperspectral Reduced Data Records (VRDRs).
Description
VRDRs are organized into 30 subdirectories named by the Mars Chart containing the VRDR, e.g. MC01. Latitude and longitude limits of Mars Charts are given in the CRISM Data Product SIS and Data Archive SIS.
A VRDR consists of several or more strips of VNIR hyperspectral mapping data mosaicked into a map tile. Thus a map tile is constructed from a large number of TRDRs. The mosaic is uncontrolled (accepting existing pointing data resulting in minor image mismatch at seams within a mosaic).

The tile contains three images: Lambert albedo summary products DDR data corresponding to Lambert albedo, augmented with additional positional information The VRDR also contains one text file, listing the wavelengths present. Each file has a separate label. For every latitude or longitude in a VRDR, there is a value of Lambert albedo corrected for atmospheric and photometric effects, plus all the information needed to provide traceability to the source data.
A global pattern of 1964 tiles each approximately 5 by 5 degrees in size is used, forming the major data product for VNIR hyperspectral mapping observations. Multiple VRDR tiles are in each of the 30 subdirectories.
