Title: Halal et al. 2023 3D HI-based Stokes Parameter Maps
The HI-based Stokes parameter maps used in (https://arxiv.org/abs/2306.10107) Filamentary Dust Polarization and the Morphology of HI Structures, Halal et al. 2023. Use of these data must cite that paper and (https://ui.adsabs.harvard.edu/abs/2019ApJ...887..136C/abstract) Clark & Hensley 2019. There are four sets of data cubes: one at Nside=1024 based on the 4' GALFA-HI data computed using the Spherical RHT algorithm, one at Nside=2048 based on the 4' GALFA-HI data smoothed to 7' computed using the Hessian algorithm, and two at Nside=1024 based on the 16.2' HI4PI data (one computed using the Spherical RHT algorithm and the other using the Hessian algorithm). A map based on the Hessian algorithm and the 16.2' HI4PI data, integrated over the velocity range -13 km/s to 16 km/s (Section 4.1 in Halal et al. 2023), is also available. The provided data cubes can be used to produce integrated maps over any velocity range desired. <br/><br/> These maps are given in units of K km/s and follow the Galactic IAU polarization convention. Multiply U by -1 to obtain maps corresponding to the COSMO convention as those provided by Planck. Multiply both Q and U by -1 to obtain maps corresponding to the magnetic field orientation in the IAU convention. <br/><br/> Please see (https://github.com/seclark/ClarkHensley2019) for code that demonstrates the use of data of the same format. The velocity binning of this data follows that of <a href="https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/P41KDE">Clark & Hensley 2019</a> and can be found <a href="https://github.com/seclark/ClarkHensley2019/tree/master/data">here</a>.  more » « less

    {"Abstract":["The intended use of this archive is to facilitate meta-analysis of the Data Observation Network for Earth (DataONE, [1]). <\/p>\n\nDataONE is a distributed infrastructure that provides information about earth observation data. This dataset was derived from the DataONE network using Preston [2] between 17 October 2018 and 6 November 2018, resolving 335,213 urls at an average retrieval rate of about 5 seconds per url, or 720 files per hour, resulting in a data gzip compressed tar archive of 837.3 MB .  <\/p>\n\nThe archive associates 325,757 unique metadata urls [3] to 202,063 unique ecological metadata files [4]. Also, the DataONE search index was captured to establish provenance of how the dataset descriptors were found and acquired. During the creation of the snapshot (or crawl), 15,389 urls [5], or 4.7% of urls, did not successfully resolve. <\/p>\n\nTo facilitate discovery, the record of the Preston snapshot crawl is included in the preston-ls-* files .

    {"Abstract":["The PPT survey extended from the Ross Ice Shelf, southward over the TAM along 150W between the Scott and Reedy Glaciers, and through the South Pole. Approximately 15,000 line km were flown. North-south oriented transects were flown 10 km apart and west-east tie lines were flown with a 30 km line spacing. Fifteen km long transect 'run-ins' and 'run-outs' were added to each line, thus ensuring data collection to survey boundaries. Laser altimetry, ice-penetrating radar, gravity and magnetic field intensity data were collected. This work was funded by NSF-OPP grant 9615832 with the project title: Collaborative Research: Contrasting Architecture and Dynamics of the Transantarctic Mountains (Pensacola-Pole Transect).

    <p><b> Introduction </b> <br> The National Science Foundations Center for Oldest Ice Exploration (<a href="https://www.coldex.org">NSF COLDEX</a>) is a Science and Technology Center working to extend the record of atmospheric gases, temperature and ice sheet history to greater than 1 million years. As part of this effort, NSF COLDEX has been searching for a site for a continuous ice core extending through the mid-Pleistocene transition. Two seasons of airborne survey were conducted from South Pole Station across the southern flank of Dome A. </p> <p><b> 2023-2024 Field Season </b> <br> In the 2023-2024 field season (CXA2), and using a BT-67 Basler, NSF COLDEX conducted 17 flights from South Pole Station toward the southern flank of Dome C. Three test flights were conducted from McMurdo Station. Instrumentation included the <a href="https://doi.org/10.18738/T8/J38CO5">60 MHz MARFA ice penetrating radar </a> from the University of Texas Institute for Geophysics, a <a href="https://doi.org/10.1109/IGARSS53475.2024.10640448">UHF ice penetrating radar </a> from the Center for Remote Sensing and Integrated Systems; an GT-2 Gravimeter, and LD-90 laser altimeter and an G-823 Magnetometer. </p> <p><b> Basal specularity content </b> <br> These basal specularity content were derived from comparing 1D and 2D focused MARFA data (<a href="http://doi.org/10.1109/TGRS.2007.897416">Peters et al., 2007</a>). By comparing bed echo strengths for different focusing apertures, and accounting for the ranges and angles involved, we can derive the "specularity content" of the bed echo, a proxy for small scale bed roughness and a good indicator for subglacial water pressure in regions of distributed subglacial water (<a href="https://doi.org/10.1109/LGRS.2014.2337878">Schroeder et al., 2014, IEEE GRSL </a>, <a href="https://doi.org/10.1016/j.epsl.2019.115961">Dow et al., 2019, EPSL </a>) and smooth deforming bed material (<a href="http://doi.org/10.1002/2014GL061645">Schroeder et al., 2014, GRL</a>, <a href="http://dx.doi/org/10.1098/rsta.2014.0297">Young et al., 2016, PTRS</a>. Specularity data are inherently noisy, so these products have been smoothed with a 1 km filter.</p>
