This dataset contains CRISM VNIR and IR Calibration Data Records (CDRs), which are used to convert data from raw DNs to units of radiance or I/F for the CRISM instrument on MRO.

This dataset is intended to include raw IR and VNIR data cubes from the CRISM instrument on MRO.

This dataset is intended to include raw IR and VNIR data cubes from the CRISM instrument on MRO.

This dataset is intended to include information on observation conditions, physical properties and coordinates of IR and VNIR data cubes from the CRISM instrument on MRO when the data cubes are pointed at Mars' surface. The information is mapped to the sensor space of non-map-projected data, EDRs and TRDRs.

This dataset is intended to include IR and VNIR data from the CRISM instrument on MRO, processed to several different levels. The core structure parallels that of an EDR with a multiband image and a text file containing frame-specific housekeeping information for each of the concatenated image frames in the multiband image. However the image data has been converted to units of radiance using level-4 and level-6 CDRs, and analog housekeeping items in the text file (voltages, currents, and temperatures) have been converted into physical units using a level-6 CDR. Both files share a common label. A TRDR may also contain separately labeled multiband images in which radiance has been processed to I/F (radiance divided by (pi * solar flux at 1 AU * heliocentric distance^2)), Lambert albedo, or a set of derived spectral parameters (summary products) that provide an overview of the data set. The summary products include Lambert albedo at key wavelengths, or key band depths or spectral reflectance ratios. To create Lambert albedo or most summary products, estimated corrections for atmospheric and photometric effects are applied to the I/F data.

This dataset is intended to include information on observation conditions of IR and VNIR data cubes from the CRISM instrument on MRO, where the data cubes are pointed at the planet limb. For surface-pointed data cubes, Derived data records are the functional counterpart. The information in LDRs is mapped to the sensor space of non-map-projected data, EDRs and TRDRs.

This dataset contains CRISM Multispectral Reduced Data Records (MRDRs). MRDRs are organized into 30 subdirectories named by the Mars Chart containing the MRDR, e.g. MC01. Latitude and longitude limits of Mars Charts are given below. An MRDR consists of several or more strips of multispectral survey 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 often resulting in image mismatch at seams within a mosaic). The tile contains up to four images: radiance extracted from temporary TRDRs Lambert albedo summary products DDR data used to generate the first three images, augmented with additional positional information The MRDR also contains up to two text files, one listing the wavelengths present and ther other listing the SPICE metakernels used for map projection of each constituent observation on the tile. Each file has a separate label. For every latitude or longitude in an MRDR, there is a radiance and all the information providing traceability to through I/F to Lambert albedo corrected for atmospheric, photometric, and thermal emission effects, plus the information needed to reconstruct the map projection. A global pattern of 1964 such tiles is being used, forming the major data product for multispectral survey observations. Multiple MRDRs are in each of the 30 subdirectories.
