Abstract We developed automated ablation stakes to measure colocated in situ changes in relative glacier-surface elevation and climatological drivers of ablation. The designs, refined over 10 years of development and deployments, implement open-source hardware and common building materials. The ablation stakes record distance to the snow/ice surface, air temperature and relative humidity every 1–15 min. Using these high-frequency data, we demonstrate that melt factors calculated using standard melt-rate vs temperature regressions converge over averaging windows of approximately 12 h or greater. Furthermore, we evaluate an integral approach to estimating temperature-index melt factors for ablation. In a test case on Glaciar Perito Moreno, Argentina, this integral approach reveals an overall positive-degree-day melt factor of 7.5 mm w.e. $^\circ$ C −1 d −1 . We describe four deployments with iteratively improved designs and provide a list of materials required to construct an automated ablation stake.

Annals of Glaciology

ANNALS OF GLACIOLOGY 在冰川学的选定方面发表原创科学文章和信件 - 对冰的研究。每一期的年鉴都是主题，集中在一个特定的主题上。国际冰川学会理事会欢迎冰川学界就主题问题提出的建议。一旦主题获得批准，理事会将任命一名副总编辑和一组科学编辑来处理论文的提交、同行评审和发表。

The Annals of Glaciology is an academic journal focused on the field of glaciology, publishing original scientific articles and letters related to the study of ice. Each issue of the journal revolves around a specific theme, and the International Glaciological Society Council welcomes suggestions from the glaciology community regarding these themes. Once a theme is approved, the Council appoints a deputy editor and a group of scientific editors to manage the submission, peer review, and publication of papers.
