Photogrammetry of a ripple field in Grand Falls Dune Field, Arizona, from December 2022 to April 2023

Our goal for this work is to place better constraints on aeolian atmospheric-surface interactions through long-term monitoring of an active, bi-modal dune field located near Grand Falls, Arizona. This dune field has been monitored since 2013 by the USGS, and data from each collection year are released as USGS Data Release products. Data described here is the photogrammetry component (raw images used to generate digital elevation models (DEMs), DEMs, and an orthomosaic of a ripple field) of the Imagery, Photogrammetry and Meterological Data from December 2022 to April 2023, Grand Falls Dune Field, Arizona USGS Data Release. Our instruments are set up near an active ripple field in the Grand Falls Dune Field. The instrument array includes a meteorological weather station that records temperature, barometric pressure, relative humidity, wind direction, wind speed, solar radiation, and precipitation every 15 minutes, and seven BlazeVideo cameras situated surrounding the ripple field that take images every 10 minutes to capture ripple migration. In addition to the deployed instruments, each time we visit the field site we also image the ripple field using a Nikon D750 (35 mm) camera. This data is processed using the software Agisoft Metashape Professional to create digital elevation models of the ripple field.
