Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Perchlorate (ClO4−) in polar ice preserves past chlorine oxidation chemistry; however, multi‐centennial Antarctic ClO4− records and the mechanisms controlling their variability remain poorly constrained. Here, we present the first 400‐year (1616−2016) ClO4− record from an Antarctic ice core, revealing two regimes separated around 1980.

Satellite‐Based Global Assessment of Solar Resource Stability
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Satellite spatial smoothing complicates comparisons of solar variability between gridded products and point measurements. We introduce the Stability Deviation Index (SDI), a bounded composite of solar intensity and intraday variability. Applied independently to 69 BSRN stations and co‐located CERES grid cells, SDI shows strong cross‐platform ...

THE BOUNCING BOULDERS OF THE ATACAMA
, 2020 124 pages ; In the heart of Chile’s Atacama Desert thousands of boulders, some exceeding 5 m in diameter, lie at the bases of steep escarpments. The rapid and forceful descents of the boulders are commonly recorded by the trails of small impact craters the boulders left as they bounced down the escarpments.
