Morphological Profiles of Sand Dunes from ICESat-2 Geolocated Photons

Aeolian process leads to the transportation and accumulation of sand particles that result in dune landforms. The structure shape dunes are driven by parameters interacting wind force material composition within. Cross-section profiles over will essay geomorphological through which steady state rate transport can be computed. National Aeronautics Space Administration’s novel satellite namely Ice, Cloud land Elevation Satellite-2 (ICESat-2) hosts a solo sensor Advanced Topographic Laser Altimeter System (ATLAS) is photon counting instrument measures round-trip time light pulse being emitted reflected back from surface determines true height topographic feature on Earth. In this article, cross-section generated beams ICESat-2 ground-tracks acquired Thar Desert region were analysed for detecting parameters. Observations have resulted giving unprecedented details about shapes morphological settings various types like barchanoids, parabolic, longitudinal, transverse dunes. Morphological length stoss slope, crest height, slip face details, inter-arms spacing, trailing arms, depositional lobes, sinuosity recurring lines retrieved with ease Level-2A data product ATL03 ICESat-2/ATLAS.
