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 imagery component (individual time-stamp images of an active ripple field) of the Imagery, Photogrammetry and Meteorological 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...

Photogrammetry techniques to quantify fine-scale topography of sand ripples with a bi-modal grain size distribution were applied to a small region of interest at Grand Falls dune field, Arizona.
Nine BlazeVideo cameras have been set up surrounding an active ripple field and meteorological station within Grand Falls dune field, Arizona. Images are taken at a set time to record sand movement. Data presented here span from April 22, 2021 to December 7, 2021.

Grand Falls dune field (GFDF) is located on the Navajo Nation, ~70 km NE of Flagstaff, AZ. This active dune field displays a range of morphologies, including barchans, smaller dunes, and ripples, and is bimodal in composition. The felsic component is likely derived from the Little Colorado River, and the mafic component (basaltic grains) is locally sourced from nearby cinder cones [1]. GFDF is an excellent analog site for both active dunes on Mars and other planetary bodies that have dune-like features (e.g., Venus and Titan). We have set up a meteorological station within the dune field that records temperature, barometric pressure, relative humidity, wind direction, wind speed, solar radiation, and precipitation...

Grand Falls dune field (GFDF) is located on the Navajo Nation, ~70 km NE of Flagstaff, AZ. This dune field has been monitored since 2013 by the U.S. Geological Survey, and data from each collection year are released as USGS Data Release products. Data described here was collected between December 2022 and April 2023. Our instruments are set up near an active ripple field in the GFDF. The instrument array includes a meteorological weather station that records temperature, barometric pressure, relative humidity, wind direction,...

Sand covers a significant portion of the Earth’s surface, including the Grand Falls area of Coconino County, AZ. The vadose zone (unsaturated zone) in a soil is of particular interest because it is broadly applicable to desert soils, which are seldom saturated and usually dry. In the absence of strong geothermal heating, the near-surface soil temperature profile is expected to exhibit maximum variation (for a given diurnal period) at the surface, with the diurnal variations becoming successively damped with depth. The temperature at a given depth is the result of diffusive heat transport vertically within the soil column. Water vapor also is expected to be transported via diffusion through the soil column [1]. We...

A meteorological station equipped with a rain gauge, atmospheric pressure sensor, temperature and relative humidity sensor, soil moisture sensor, and an anemometer (measuring wind speed, gust speed, and direction) was deployed at Grand Falls dune field, Arizona. This dataset has been collecting data every 15 minutes with the goal to provide context for ripple and dune migration at an active dune field site.

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. Photogrammetry was carried out across a small section of the active ripple field in which the BlazeVideo cameras are positioned around. This set of data includes raw images used to generate digital elevation models (DEMs), DEMs, orthomosaics, and metashape reports for each collection date. Our instruments are set up near an active...

These data include geospatial files (shapefiles and orthorectified raster images) and an input hydrograph (csv) for a 1-dimensional unsteady hydrologic model. Shapefiles consist of active channel boundarys and channel centerlines of six reaches of the LCR beginning ~4.5 km above Grand Falls, AZ, and ending ~12.8 km downstream from Cameron, AZ. These reaches are (1) the ~4.5 km above Grand Falls reach, (2) the 1.5km below Grand Falls reach, (3) the ~18.8 km Black Falls reach, (4) the ~16.5 km above Cameron reach, (5) the ~4.7 km Cameron to Moenkopi reach, and (6) the ~8.1 km below Moenkopi reach. Raster images consist of orthorectified aerial photograph mosaics between 1933/34 and 1992. Scans of the images were acquired...
