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 small cinder field in Sunset Crater National Monument, Arizona (SUCR) and deployed temperature...

We created a single map of surface water presence by intersecting water classes from available land cover products (National Wetland Inventory, Gap Analysis Program, National Land Cover Database, and Dynamic Surface Water Extent) across the U.S. state of Arizona. We derived classified samples for four wetland classes from the harmonized map: water, herbaceous wetlands, wooded wetlands, and non-wetland cover. In Google Earth Engine (GEE) we developed a random forest model that combined the training data with spatially explicit predictor variables of vegetation greenness indices, wetness indices, seasonal index variation, topographic variables, and hydrologic parameters. The final product is a wall-to-wall map of...

This was a test of equipment and methodology prior to remote field work. We inserted the probes of temperature data loggers into the cinder-covered surface within a scene being observed by a FLIR thermal camera. The temperature probes record near-surface temperatures while the thermal camera records at-surface temperatures. Comparisons between the 2 thermal datasets can be used for calibration and to determine physical properties such as thermal conductivity.
A thermal camera has been set up next to a meteorological station at a small cinder field in Sunset Crater National Monument, Arizona. Images were acquired every minute. Data presented here include .jpg thermal images and corresponding .csv files containing image temperatures where each cell represents the temperature of a pixel in the image. Data were collected on March 24, 2022.
