A multi-method Antarctic atmospheric blocking dataset (1979–2024)

Deniz Bozkurt, Charlie Opazo, Julio C. Marín, Kyle R. Clem et autres

Atmospheric blocking is a key driver of persistent circulation anomalies and associated extreme events in the Southern Hemisphere, yet its characteristics around Antarctica remain poorly understood due to methodological diversity and the absence of a consolidated, long-term dataset. This study presents a …

A multi-method Antarctic atmospheric blocking dataset based on ERA5 (1979–2024)

Deniz Bozkurt, Charlie Opazo, Julio César Marín, Kyle R. Clem et autres

Version 2.0, July 2026. This release supersedes Version 1 and updates the percentile-based blocking methodology. For each calendar day, the local 90th-percentile threshold is calculated from anomalies within a centred 15-day running window (±7 days), pooled across all reference years. This approach …

QFuego-Patagonia: A comprehensive glacier-related dataset for Patagonia and Tierra del Fuego, South America

David Farías-Barahona, Matthias Braun, Marius Schaefer, Shin Sugiyama et autres

Abstract Patagonia and Tierra del Fuego (Austral Andes) are the most glacierised regions in the Southern Hemisphere, where glaciers have experienced significant mass changes in recent decades. Understanding glacier–climate–water interactions is crucial for addressing future climate challenges. Open-access data play a key …

Hyperdroughts in central Chile: drivers, impacts, and projections

René Dario Garreaud, Juan Pablo Boisier, Camila Álvarez-Garretón, Duncan A. Christie et autres

Owing to the Mediterranean-like and highly variable climate of western South America, moderate droughts (20 %–30 % precipitation deficit) recur every 3–5 years in central Chile, alternating with wet years. Since 2010, however, this region has experienced a continuous dry spell, including …

The key role of extreme weather and climate change in the occurrence of exceptional fire seasons in south-central Chile

Tomás Carrasco-Escaff, René Dario Garreaud, Deniz Bozkurt, Martín Jacques‐Coper et autres

Unprecedentedly large areas were burned during the 2016/17 and 2022/23 fire seasons in south-central Chile (34-39°S). These seasonal-aggregated values were mostly accounted for human-caused wildfires within a limited period in late January 2017 and early February 2023. In this paper, we provide …
