A new study presents a nine-Martian-year survey of dust and water ice clouds vertical distribution, key drivers of the planet’s climate.
Taking the Pulse of Atmospheric Drag to Predict Satellite Trajectory
Scientists present a new method for estimating the density of the upper atmosphere to account for atmospheric drag when predicting satellite trajectory.
Let’s Not Forget About Long Droughts
Why do conceptual hydrologic models struggle to model long-term droughts? A new study investigates.
Drone Imagery Reveals Marked Variability in Antarctic Snow Roughness
Multi-temporal UAV oblique photogrammetry reveals significant fine-scale variability in Antarctic snow roughness driven by surface type, measurement scale, model choice, and meteorological conditions.
Drivers of Day-to-Day Temperature Swings Across Continents
Abrupt temperature swings aren’t random—large-scale air mass shifts and seasonal processes drive day-to-day variability across major Northern Hemisphere regions.
Managed Agriculture Hinders Predictability of Critical Zone Features
Intensively managed agricultural sites show behavioral shifts of the critical zone system and subsystems thus impacting predictability.
Toward Marine Cloud Brightening at Scale: A Science Agenda
Marine Cloud Brightening (MCB) is a Solar Radiation Management (SRM) solution to cool the planet by changing the albedo of low-altitude marine clouds to increase reflected shortwave radiation.
How Space Plasma Can Bend the Laser of Gravitational Wave Detectors
A new study reveals how and to what extent laser beams are bent during propagation through space plasma in TianQin, a geocentric space-borne gravitational wave detector.
Gravity Waves Help Drive Sediment to the Deep Ocean
Laboratory experiments reveal that gravity wave-turbidity current interactions (combined flows) can enhance sediment transport to the deep ocean.
More Braided Rivers from Increasing Flow Variability
Global analysis of satellite data and river flow records show that higher flow intermittency after climate change may lead to an increasing number of threads in braided rivers, thus impacting ecosystems.
Weather Radar Data Reveal the Dynamics of Rapidly Spreading Wildfires
New research demonstrates the use of operational weather radar measurements to track long-range ember fallout and rapid spread of intense wildfires.
Choice of Glen’s n Leads to Differing Projections of Ice Sheet Mass Loss
Glen’s Law describes the simple physics of ice flow that underpins ice sheet models, but parameter choices substantially influence the outcome of model projections.
