Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated

Observation of a Downward Terrestrial Gamma‐Ray Flash Associated With Dart Leaders of a Negative Cloud‐To‐Ground Lightning Flash

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract We report the observation of a downward terrestrial gamma‐ray flash (TGF) during the dart‐leader stage in a negative cloud‐to‐ground lightning flash. The observation was recorded by the Telescope Array Surface Detector, in conjunction with a Lightning Mapping Array, an interferometer (INTF), a fast antenna, and a high‐speed camera.
