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 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 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 volume contains the CRISM Map-projected Targeted Reduced Data Record (MTRDR) archive, a collection of multiband image cubes derived from targeted (gimbaled) observations of Mars' surface acquired by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument on the Mars Reconnaissance Orbiter (MRO) spacecraft. Post-processing attempts to represent the spectrum the instrument would have measured looking at the surface of Mars at a standard illumination geometry, in the absence of atmospheric gases, with aerosol scattering normalized to that at the geometry within the observation that is closest to nadir, in the absence of instrument artifacts. A series of value added products represent spatial variability in signatures of minerals of interest. The data are map projected using terrain models of the Martian surface. A companion Targeted Empirical Record (TER) archive contains mostly the same data in the sensor space of the IR detector to support map projection using future more accurate terrain models.
