| Summary: | Datasets from Xiao et al. (2022, in revision with Planetary and Space Science) titled "Prospects for Mapping Temporal Height Variations of the Seasonal CO2 Snow/Ice Caps at the Martian Poles by Co-registration of MOLA Profiles". An initial version of the manuscript can be accessed at https://arxiv.org/abs/2109.04899.## abbreviationsMars Orbiter Laser Altimeter (MOLA)Digital Terrain Model (DTM)University College London (UCL)High-Resolution Stereo Camera (HRSC)MOLA_reference_DTM_from_self_registration.tif is the reference DTM generated from self-registration of the reprocessed MOLA profiles. The heights are references to a Martian sphere of 3396 km. It covers the region poleward of 78°S with a resolution of 500 m/pixel. Projection is polar stereographic centered at the South Pole. Number_footprints_per_pixel_MOLA_reference_DTM.tif is the map that demonstrates the number of available MOLA footprints (after reprocessing and self-registration) within each of the grid element for the generation of MOLA_reference_DTM_from_self_registration.tif.The original UCL HRSC DTMs at the Martian South Pole, with a gridding resolution of 50 m/pixel, can be accessed at https://www.cosmos.esa.int/web/psa/UCL-MSSL_iMars_HRSC_v1.0.

A New South Polar Digital Terrain Model of Mars from the High-Resolution Stereo Camera (HRSC) onboard the ESA Mars Express. Planetary and Space Science, 174, 43-55.UCL_HRSC_DTMs_mosaic_after_alignment_to_MOLA_reference.tif is the mosaic of these UCL HRSC DTMs after being aligned to the self-registered MOLA profiles, which are used to generate MOLA_reference_DTM_from_self_registration.tif. Grid size is 50 m/pixel with a stereographic projection centered at South Pole.Height_difference_before_alignment.tif and Height_difference_after_alignment.tif show the relative height differences between these HRSC DTMs and the self-registered MOLA profiles before and after the alignment, respectively.
