High Geomagnetic Reversal Frequency During the Middle to Late Ediacaran (∼570 Ma) Constrained by Integrated Magneto‐ and Cyclostratigraphy

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Ediacaran–Cambrian (∼635–539 Ma) geomagnetic field is characterized by unusually high reversal rates and markedly weakened field strength. Estimates of these reversal frequencies can reveal key aspects of deep Earth dynamics and their potential influence on surface environments and early complex life.

Impacts of Low‐Level Jets on Moisture Transport to the Pantanal, Brazil

open access: yesInternational Journal of Climatology, Volume 46, Issue 3, 15 March 2026.
The moisture transports from the tropics to the subtropics by the low‐level jets (LLJs) east of the Andes crossing the Pantanal region. Four LLJs, east of the Andes, were identified and selected with correspondent Lagrangian moisture transport. The LLJ moisture source regions contribute to Pantanal (~63.5%) and precipitation increased (~30%) during LLJ

Comparative ozone production sensitivity to NOx and VOCs in Quito, Ecuador, and Santiago, Chile [PDF]

open access: yesAtmospheric Chemistry and Physics
Amid the current climate and environmental crises, cities are being called to reduce levels of atmospheric pollutants that also act as short-lived climate forcers, such as ozone and PM2.5. This endeavor presents new challenges, especially in understudied

Suprathermal Soliton Solutions to Nonlinear Schrödinger Equation

open access: yesContributions to Plasma Physics, Volume 66, Issue 3, March 2026.
ABSTRACT Maxwell distributions are very difficult to find in the low‐pressure environment far away the Earth atmosphere, permeated by high temperatures, various types of radiation, highly energetic particles, space debris, and subjected to microgravity, presenting crucial challenges for spacecraft design and operations, and affecting astronaut's health.
