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 since December 15, 2020 with the goal to provide context for ripple and dune migration at an active dune field site.

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.

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 have selected a sand sheet within the Grand Falls Dune Field (GFDF) and deployed temperature and relative humidity sensors at 5 different depths: 1, 6, 12, 24, and 48 cm to capture diurnal temperature and humidity variations.

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. 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.

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.
