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 every 15 minutes during the windy season and every hour during the calmer months. Nine BlazeVideo cameras have been set up near the meteorological station, surrounding an active ripple field to capture ripple migration. Images are taken at a set time to record sand movement. Ripples are also imaged using a NIKON D250 camera, in which data is then processed using the software Agisoft Metashope Professional to create digital elevation models of the ripple field. Data presented here span from December 2021 to December 2022. [1] Hayward, R. K. et al. (2010) 2nd Int. Plan. Dunes Wrkshp., Abstract #2004.

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. In addition, an array of temperature and relative humidity sensors were deployed at five different depths within the soil to capture diurnal temperatures and humidity variations. This array is located near the meteorological station and both sets of instruments collect data every 15 minutes. A set of cameras have been positioned near an active ripple field, ~7 m southeast of the meteorological station. The cameras take images every 10 minutes to monitor ripple movement. A series of images were also taken using a NIKON D250 camera, in which data were then processed using the software Agisoft Metashope Professional to create a digital elevation model of the ripple field.

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 meteorological component 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 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.

We deployed a meteorological weather station at GFDF that records temperature, barometric pressure, relative humidity, wind direction, wind speed, solar radiation, and precipitation every 15 minutes.

Ripple images of a small region within GFDF were acquired using a NIKON D250 DSLR camera, then processed through Agisoft Metashope professional photogrammetry software to create digital elevation models (DEMs) of the ripple field. The DEMs included here represent dates between 02-20-2024 to 07-25-2024. The photogrammetry component therefore comprises seven zipped folders, each containing a DEM (digital elevation model), an orthomosaic, colorized shaded relief (all TIFF files), and a processing report (PDF) labeled with the day data was collected.

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.
