Ensemble Learning Estimates Terrestrial Water Storage Changes
Ensemble learning models for estimating past changes of terrestrial water storage from climate are presented and tested in the Pearl River basin, China.
How Accurate Are Our Measurements of the Sun’s Energy?
As instruments collecting solar data degrade, researchers must correct for errors. A new study compares several methods to correct solar spectral irradiance measurements.
Mapping Martian Dunes from Orbit
New research shows how fast the sands shift on the Red Planet and how useful imagery from different orbiting cameras can be in studies of Mars’s dunes.
Evaluating Cloud Cover Predictions in Climate Models
A new analysis highlights progress in predictions of cloud cover from models that are part of the Coupled Model Intercomparison Project.
Observational Data Validate Models of Sun’s Influence on Earth
Using a combination of independent models and observations over multiple timescales, scientists verify two important models that gauge the amount of solar radiation Earth receives.
A Better Way to Measure Cloud Composition
An enhanced satellite remote sensing suite accurately measures ice particles, temperature, and water vapor.
The Ups and Downs of Rainfall in Chad Since 1950
A new study finds that rainfall rates are recovering in some cities since a 1966–1990 dry spell, but precipitation is still down overall since 1950.
Celebrating a Century of Nonlinearity Across the Geosciences
Nonlinear concepts have evolved and become increasingly applicable to a wide range of geoscience inquiries, thus setting the stage for exciting new advances during AGU’s next 100 years.
Extending the Record of Surface Melt on the Larsen C Ice Shelf
The first use of Advanced Scatterometer radar data to determine melt duration on an Antarctic ice shelf shows the season has decreased by up to 2 days per year during the extended 21st century record.
