Capturing complex star dune dynamics - Repeated highly accurate surveys combining multitemporal 3D topographic measurements and local wind data [Data]
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Morphologies of highly complex star dunes are the result of aeolian dynamics in past and present times. These dynamics reflect climatic conditions and associated forces like sediment availability and vegetation cover as well as feedbacks with adjacent environments. However, an understanding of aeolian dynamics on star dune morphometries is still lacking sufficient detail and their influence for formation and evolution remain unclear. We therefore investigate dynamics of a complex star dune (Erg Chebbi, Morocco), by analyzing wind measurements compared to morphometric changes derived from multitemporal high-accuracy 3D observations during two surveys (October 2018 and February 2020). Using Real-Time Kinematic Global Navigation Satellite System (RTK-GNSS) measurements and Terrestrial Laser Scanning (TLS), the reaction of a star dune surfac' .
