Data Set Overview : This data set contains data that will help determine the mineralogy of Martian rocks and soils, determine the thermophysical properties of soil patches, and determine the temperature profile, dust opacity, water-ice opacity, and water vapor abundance in the lower boundary layer of the Martian atmosphere. The Mini-TES calibrated radiance is the primary data product for the MER mission. These data will be converted to effective emissivity and surface temperature by fitting a Planck blackbody function to the calibrated spectrum. The emissivity spectra will be converted to mineral abundance using a linear deconvolution model and a matrix of mineral spectra from the ASU Mineral Library and other sources. The derived surface temperature will be used to produce thermal inertia images via a thermal model, using data from multiple times of day where possible Attempts will be made to coordinate these diurnal observations with the times of TES or THEMIS direct overflights, providing simultaneous temperature observations that can be extended to broader regions surrounding the rovers.  The Mini-TES will also view upward at angles up to 30 degrees above the horizon to provide high-resolution temperature profiles of the Martian boundary layer. This upward-viewing mode will yield high- resolution temperature profiles through the bottom few km of the atmosphere using temperatures retrieved from the wings of the 15-mm CO2 band. This lowest region of the atmosphere has been difficult to measure on Mars because of the nature of the weighting functions as seen from orbit, and because of the difficulty of determining surface contributions to radiance.  Atmospheric water abundance will be obtained by vertical and horizontal viewing of rotational H2O lines. Separate measurements of water near the ground will be obtained by viewing distant surface obstacles. The broad water-ice feature centered near 800 cm^-1 will allow monitoring of ground ice hazes. Together, these measurements will illuminate the behavior of water in lower atmosphere and of water transport between the atmosphere and surface. Atmospheric dust abundance will be obtained using the redundant temperature information in both sides of the 15 mm CO2 band, together with differential absorption across the dust band in that region.   Processing : The Mini-TES data products comply with NASA processing level standards. All Mini-TES products are spectral image QUBEs derived from the previous level product.  RDRs, BTRs, and EMRs will be produced in succession by the Mini-TES Team and placed into the OSS for distribution. If a data product needs to be regenerated for any reason, the original version will be overwritten with the new version. The new version may have a version number revision in the file name and will contain updates to keyword values and History objects within the header.   Data : Each Mini-TES data product consists of a single file of header objects attached to a spectral cube. There are 4 fundamental parts of a data product:  1) an attached PDS label in ASCII format, composed of keyword-value pairs  2) a History object, describing the processing history that the data product has gone through; this ASCII object is a set of ODL statements, similar to the PDS keyword-value pairs  3) a table of binary, fixed-length records (available in EDRs only); table records are the internal calibration spectra and their associated telemetry values  4) a spectral cube, containing either interferogram data or radiance spectra and organized by azimuth and elevation with housekeeping and telemetry values attached as suffix backplanes  The size of a data product will vary from sequence to sequence depending upon the size of the image commanded and the processing level completed. The average expected size of the data in an EDR from a 2-hour panoramic scan will be approximately 1.7MB.   Software : ASU has provided data processing software, called 'calibrate_qube', which converts EDR data into calibrated RDR data and the successive higher level data products: BTR and EDR. If necessary, interferogram data are converted via FFT into raw radiance spectra. Raw radiometric data is calibrated using available calibration target observations, both internal and external, and the known Mini-TES instrument response function as described in 'The Mini-TES Data Processing Guide'. The calibration software is executed on the ASU hyper-spectral analysis system called Davinci.   Media/Format : The data set will initially be delivered and kept online. Upon Mission completion, the Mini-TES RDRs will be delivered to PDS on DVD.
