MRO CRISM MULTISPECTRAL REDUCED DATA RECORD V1.0

The tile contains up to five images: I/F extracted from TRDRs Lambert albedo summary products DDR data corresponding to the I/F and/or Lambert albedo, augmented with additional positional information The MRDR also contains one text file, listing the wavelengths present. Each file has a separate label. For every latitude or longitude in an MRDR, there is a value of I/F and/or Lambert albedo corrected for atmospheric and photometric effects, plus all the information needed to provide traceability to the source data.

For the first two of three versions of the map, while detailed corrections for instrumental and atmospheric effects were still under development (v1, v3), I/F from source TRDRs was included. In v1 and the final version (v4) corrected Lambert albedo is included. A global pattern of 1964 tiles each approximately 5 by 5 degrees in size is used, forming the major data product for multispectral survey observations.

Multiple MRDRs tiles are in each of the 30 subdirectories.
