Time series analyses of solute concentrations in streamwater and precipitation are powerful tools for unraveling the interplay of hydrological and biogeochemical processes at the catchment scale. While such datasets are available for many sites around the world, they often lack the necessary temporal resolution or are limited in the number of solutes they encompass. Here we present a multi-year dataset encompassing daily records of major ions and a range of trace metals in both streamwater and precipitation in three catchments in the northern Swiss Pre-Alps. These time series capture the temporal variability observed in solute concentrations in response to storm events, snow melt, and dry summer conditions. This dataset additionally includes stable water isotope data as an extension of a publicly available isotope dataset collected concurrently at the same locations, and together these data can provide insights into a range of ecohydrological processes and enable a suite of analyses into hydrologic and biogeochemical catchment functioning.
时间序列分析地表水和降水的溶质浓度是揭示流域尺度水文和生物地球化学过程相互作用的有力工具。虽然世界各地有许多站点都提供了此类数据集，但它们通常缺乏必要的时间分辨率，或者所涵盖的溶质数量有限。在这里，我们展示了一个多年数据集，其中包含了瑞士北部前阿尔卑斯山三个流域的地表水和降水中主要离子和一系列痕量金属的每日记录。这些时间序列捕捉到了溶质浓度在应对风暴事件、融雪和干燥夏季条件下的时间变化。该数据集还包括稳定水同位素数据，作为同时在同一地点收集的公开可用同位素数据集的扩展，这些数据可以深入了解一系列生态水文学过程，并支持一系列对水文和生物地球化学流域功能的分析。
