Global Observations of Acetyl Peroxynitrate (PAN) in the Remote Troposphere

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract We present global airborne observations of acetyl peroxynitrate (CH3C(O)OONO2, PAN) in the remote troposphere from the Atmospheric Tomography (ATom) campaign. These observations show that biomass burning is the dominant source of PAN in the Southern Hemisphere (SH).

Experimental Investigation of Mercury's Outer Core

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract The liquid outer core of Mercury is fundamental to sustaining its dynamo. The intrinsic magnetic field depends strongly on the metal composition and related physical properties. The composition in turn is influenced by inner core crystallization and interactions with the adjacent reduced mantle.

Log‐Periodic Power Law Singularities in Landslide Dynamics: Statistical Evidence From 52 Crises

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract Landslide movements typically show a series of progressively shorter quiescent phases, punctuated by sudden bursts during an acceleration crisis. We propose that such intermittent rupture phenomena can be described by a log‐periodic power law singularity model. Amounting mathematically to a generalization of the power law exponent from real to

Fluorescence Efficiency‐Derived Physiological Optimal Temperature Improving the Estimation of Photosynthesis

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract Terrestrial gross primary production (GPP) quantifies the rate of CO2 fixation in ecosystems through photosynthesis. The optimal temperature (Topt) is one of fundamental determinants in the vegetation photosynthesis model (VPM) model that constrains the temperature response of light use efficiency (LUE) under changing environmental conditions.

Seismic Tremors From Sea‐Landfast Ice Interactions Near Utqiaġvik, Alaska

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract The mechanical state of Arctic landfast sea ice remains poorly constrained due to limited observations. This study investigates interactions between drifting sea ice and the coastal landfast ice near Utqiaġvik, Alaska by integrating data from broadband seismometer, Distributed Acoustic Sensing, and marine radar.
