A Closure on Sea Level Rise Budget

by Valeriy Ivanov 27 November 201928 October 2021

Terrestrial water loss may explain the lack of previous budget closure in global mean sea level rise.

Extreme Summer Heat over Europe Is Predictable Week-to-Week

by Alessandra Giannini 26 November 201914 February 2023

Forecasts made one to a few weeks in advance, known as “subseasonal to seasonal” predictions, show more skill in predicting extreme summer heat waves over Europe than spells of normal or cold weather.

Submarine Rivers of Sediment

by A. M. Hogg 14 November 201914 March 2024

Turbidity currents move suspended sediment into the ocean. In general, the more sediment, the stronger the turbidity current, but one process may generate turbidity currents from very dilute rivers.

Examining the Structure of Tropical Cyclones’ Upper Levels

by Suzana Camargo 12 November 20198 March 2022

Unique observations used to examine the structure and mass balance of hurricanes’ top levels find that regions of high pressure violate the gradient wind balance.

Explaining the Missing Energy in Mars’s Electrons

by Mark Zastrow 11 November 201910 March 2022

Electrons energized and trapped at Mars were thought to lose energy inside the planet’s magnetosheath, but new research suggests a different explanation of spacecraft data.

Where Does the Carbon Go When Permafrost Coasts Erode?

Kate Wheeling, freelance science writer by Kate Wheeling 7 November 20199 December 2021

Arctic coastlines have not been considered carefully in carbon cycles for long, but new research suggests that eroding permafrost may emit more greenhouse gases than previously thought.

Thermal Convection Can Power the Geodynamo

by S. D. Jacobsen 4 November 201910 March 2022

New high-pressure experiments on fluid iron suggest thermal convection without compositional buoyancy is sufficient to drive the dynamo generating Earth’s magnetic field.

Machine Learning Improves Satellite Rainfall Estimates

by Valeriy Ivanov 31 October 201925 July 2022

A new deep learning approach bridges ground rain gauge and radar data with spaceborne radar observations of Tropical Rainfall Measuring Mission to improve precipitation estimation.

Future Remote Sensing Mission Holds Promise for Flood Monitoring

by Valeriy Ivanov 28 October 20191 December 2022

The 2021 Surface Water and Ocean Topography (SWOT) mission will measure water surface elevation, slopes, and inundations of rivers as narrow as 50 meters.

Earthquake Statistics Vary with Fault Size

Aaron Sidder, freelance science writer by Aaron Sidder 21 October 20197 October 2022

A theoretical study explores why small earthquake sources can produce quasiperiodic sequences of identical events, whereas earthquakes on large faults are intrinsically more variable.
