Improved Representation of Surface Emissivity Effects on Longwave Radiation in a Coupled Earth System Model
Lili Manzo + Charles S Zender + Erin E Thomas ...
Many Earth System Models (ESMs) approximate surface emissivity as constant over all wavelengths (broadband). This approximation misrepresents the spectral distribution of...

Evolution of Atmospheric Oxygen Escape From Earth Since the Great Oxidation Event
Maria Luisa Alonso Tagle + Aline Vidotto + Caue Borlina ...
The present study reconstructs the evolution of Earth's oxygen escape into space since the Great Oxidation Event, approximately 2450 Myr ago. We use a semi‐empirical model...

Generation of Falling‐Tone Whistler‐Mode Chorus Waves in the Earth's Magnetosphere
Huayue Chen + Hong Zhao + Lunjin Chen ...
Chorus waves are intense whistler‐mode emissions in space that play a key role in regulating energetic electron dynamics in the hazardous radiation belt. While rising‐tone...

1.5‐Year Periodic Variations in the Equatorial Components of the Earth's Figure Axis and Their Dynamical Response to Major Climate Modes
HONGJUAN YU + Krzysztof Jakub Sosnica + Longjiang tang ...
Temporal variations in the equatorial components of the Earth's figure axis, represented by the second‐degree, first‐order Stokes coefficients (ΔC21 and ΔS21), reflect large‐scale...

Evolution of Sulfur Concentration in the Deep Earth During the Proto‐Earth Growth: First‐Principles Study on the Sulfur Partitioning Between Metal and Silicate at High Pressure and
Kei Ito + Taku Tsuchiya
Sulfur (S) is one of the promising light elements that can explain the density deficit of the core. The degree of siderophile nature of S under high pressure and temperature...
