Short summary

A low latitude-high altitude Alpine ice core record was obtained in 2011 from the glacier Alto dell’Ortles (Eastern Alps, Italy) and provided evidence of one of the oldest Alpine ice core records spanning the last ~7000 years, back to the last Northern Hemisphere Climatic Optimum. Here we provide a new Alto dell’Ortles chronology of improved accuracy that will allow to constrain Holocene climatic and environmental histories emerging from this high-altitude glacial archive of Central Europe.
