Monitoring of the periglacial environment is relevant for many disciplines including glaciology, natural hazard management, geomorphology, and geodesy. Since October 2022, Rock Glacier Velocity (RGV) is a new Essential Climate Variable (ECV) product within the Global Climate Observing System (GCOS). However, geodetic surveys at high elevation remain very challenging due to environmental and logistical reasons. During the past decades, the introduction of low-cost global navigation satellite system (GNSS) technologies has allowed us to increase the accuracy and frequency of the observations. Today, permanent GNSS instruments enable continuous surface displacement observations at millimetre accuracy with a sub-daily resolution.In this paper, we describe decennial time series of GNSS observables as well as accompanying meteorological data. The observations comprise 54 positions located on different periglacial landforms (rock glaciers, landslides, and steep rock walls) at altitudes ranging from 2304 to 4003 ma.s.l. and spread across the Swiss Alps. The primary data products consist of raw GNSS observables in RINEX format, inclinometers, and weather station data. Additionally, cleaned and aggregated time series of the primary data products are provided, including daily GNSS positions derived through two independent processing tool chains.The observations documented here extend beyond the dataset presented in the paper and are currently continued with the intention of long-term monitoring. An annual update of the dataset, available at https://doi.org/10.1594/PANGAEA.948334 (Beutel et al., 2022),​​​​​​​ is planned. With its future continuation, the dataset holds potential for advancing fundamental process understanding and for the development of applied methods in support of e.g. natural hazard management.

使用 GNSS 仪器对瑞士冰缘环境进行原位观测,使用 GNSS 仪器对瑞士冰缘环境进行原位观测

冰缘环境监测与许多学科相关,包括冰川学、自然灾害管理、地貌学和大地测量学。自 2022 年 10 月起,岩石冰川速度 (RGV) 成为全球气候观测系统 (GCOS) 中的一项新的基本气候变量 (ECV) 产品。然而,由于环境和后勤原因,高海拔的大地测量仍然非常具有挑战性。在过去几十年中,低成本全球导航卫星系统 (GNSS) 技术的引入使我们能够提高观测的准确性和频率。今天,永久性 GNSS 仪器能够以亚日分辨率以毫米精度连续观测地表位移。在本文中,我们描述了 GNSS 观测值的十年时间序列以及伴随的气象数据。 一个...并遍布瑞士阿尔卑斯山。主要数据产品包括 RINEX 格式的原始 GNSS 可观测数据、测斜仪和气象站数据。此外,还提供了主要数据产品的清理和聚合时间序列,包括通过两个独立处理工具链得出的每日 GNSS 位置。此处记录的观察结果超出了本文中提供的数据集,目前仍在继续,目的是长期监控。数据集的年度更新计划可在 https://doi.org/10.1594/PANGAEA.948334(Beutel等人,2022 年)获得。随着其未来的延续,该数据集有可能促进对基本过程的理解和开发支持自然灾害管理等应用方法。,冰缘环境监测与许多学科相关,包括冰川学、自然灾害管理、地貌学和大地测量学。自 2022 年 10 月起,岩石冰川速度 (RGV) 成为全球气候观测系统 (GCOS) 中的一项新的基本气候变量 (ECV) 产品。然而,由于环境和后勤原因,高海拔的大地测量仍然非常具有挑战性。在过去几十年中,低成本全球导航卫星系统 (GNSS) 技术的引入使我们能够提高观测的准确性和频率。今天,永久性 GNSS 仪器能够以亚日分辨率以毫米精度连续观测地表位移。在本文中,我们描述了 GNSS 观测值的十年时间序列以及伴随的气象数据。 一个...并遍布瑞士阿尔卑斯山。主要数据产品包括 RINEX 格式的原始 GNSS 可观测数据、测斜仪和气象站数据。此外,还提供了主要数据产品的清理和聚合时间序列,包括通过两个独立处理工具链得出的每日 GNSS 位置。此处记录的观察结果超出了本文中提供的数据集,目前仍在继续,目的是长期监控。数据集的年度更新计划可在 https://doi.org/10.1594/PANGAEA.948334(Beutel等人,2022 年)获得。随着其未来的延续,该数据集有可能促进对基本过程的理解和开发支持自然灾害管理等应用方法。
