Reassessing Methanesulfonic Acid as a Sea Ice Proxy: An Example From the Weddell Sea Sector

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Antarctic sea ice has declined since 2015, but placing this trend in a longer‐term context remains challenging. Ice core methanesulfonic acid (MSA) offers a potential record of sea ice variability beyond the instrumental period, yet its applicability in sectors including the Weddell Sea remains unclear.

Multidecadal Changes in Atmospheric Dryness Over East Asia Dominated by Internal Climate Variability

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Summer near‐surface vapor pressure deficit (VPD), a key measure of atmospheric dryness, has increased markedly across East Asia since 1980, yet the relative roles of external forcing and internal variability (IV) in its multidecadal changes remain unclear.

High‐Resolution Temperature and Precipitation Variability in Northeast Asia Since the Last Glacial Maximum Recorded in an Annually Laminated Maar Lake

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Temperature and precipitation variability in monsoonal Asia is central to understanding regional climate dynamics and global teleconnections. How post‐LGM warming and hydroclimate change unfolded in Northeast Asia, and how they were linked to external forcing, remain poorly constrained.

How Can the Latent Heat Entrainment Flux in the Convective Boundary Layer be Characterized?

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract A proposed theoretical description of the latent heat entrainment flux at the top of a convective boundary layer (CBL) was tested. It is related to the vertical velocity scale times the ratio of the water vapor mixing ratio (WVMR) gradient to the Brunt‐Väisälä frequency. This relation was tested with different LiDAR and radiosonde measurements.

Multifractal detrended fluctuation analysis of temperature in Spain (1960–2019)

open access: yes
In the last decades, an ever-growing number of studies are focusing on the extreme weather conditions related to the climate change. Some of them are based on multifractal approaches, such as the Multifractal Detrended Fluctuation Analysis (MF-DFA ...

Meter‐Scale Roughness of the Lunar Surface

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Small‐scale surface roughness is a key indicator of local geological processes, yet it has not previously been mapped globally on the Moon. We present global meter‐scale surface roughness maps generated from the Lunar Orbiter Laser Altimeter pulses, which record information about surface undulations within the instrument's ∼5 m individual ...

The Growing Role of Evaporative Demand in Driving Record‐Breaking Droughts in the Amazon Basin

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Amazon droughts have historically been driven by precipitation deficits, but recent escalating drought events highlight a regime shift toward “hot droughts.” By decomposing historical drought drivers (1979–2024), we show that rising evaporative demand (represented by potential evapotranspiration, PET) now acts as a primary driver of drought ...
