The ILAMB System for Benchmarking Land Surface Models
An evolving set of tools helps land surface model developers optimize the realism of their parameterizations for the next generation of weather and climate models.
How Old Is the Mekong River Valley?
Granite samples collected from the Mekong River Valley reveal that the river’s path was incised roughly 17 million years ago, most likely by increased erosion from monsoon precipitation.
Subsurface Imaging Sheds Light on Dead Sea Sinkholes
Using seismic waves, researchers study sediment layering near the Dead Sea to reveal how the area’s numerous sinkholes form.
A Landscape Shaped by Wind
High-altitude aeolian research on the Tibetan Plateau offers insights into the past, present, and future.
Tracking Deep-Earth Processes from Rapid Topographic Changes
Rapid elevation-rise in Turkey, tracked by marine sediments that now sit at 1.5 km in elevation, is linked to deep-Earth processes that can explain short-lived, extreme rates of topographic change.
A New Baseline to Monitor Earth’s Dynamic Surface
Researchers devise a new mathematical approach to combine space- and ground-based observations into an alternative reference frame for monitoring the changing positions of Earth’s features.
The Competing Climate Effects of Elevation and Albedo
Variations in surface reflectivity are as important as surface elevation changes in determining regional climate at nonpolar latitudes, according to a new modeling study.
New Tool for Understanding Landscape Evolution in Drylands
Combining vegetation distribution models and sediment transport models offers a better understanding of how dryland environments change in response to different factors.
Lab Tests Probe the Secrets of Steep and Rocky Mountain Streams
Researchers built a glass-encased test environment that helps them assess streamflow without the confounding factors introduced by bed forms.
