North Temperate Lakes LTER Estimated winter inputs of stream water and groundwater to primary study lakes 1982 - 2014

This data set integrates and summarizes daily surface and groundwater inputs to 5 primary study lakes, using model estimates from a data-driven USGS hydrologic model (Hunt et al. 2013; Hunt and Walker 2017), and ice phenology data (number of days since ice-on). The lakes are Allequash, Big Muskellunge, Crystal, Sparkling, and Trout. Powers et al. (2017) used these data to estimate upper and lower bounds for exogenous chemical inputs to the lakes during winter. For a given lake and winter year, cumulative surface water and groundwater inputs were calculated across the ice cover period. For each lake, this data set reports the mean, maximum, and minimum winter water inputs observed across years, in units of water volume, % of average lake volume, and volume per winter day. Sampling Frequency: 1 per lake, with multiple summary values reported (i.e., mean, min, max). Number of sites: 5. Hunt, R.J. et al., 2013.

本数据集整合并汇总了5个核心研究湖泊的每日地表与地下水输入量，所用数据源自美国地质调查局（USGS）数据驱动水文模型的估算结果（Hunt等，2013；Hunt与Walker，2017），同时纳入了冰物候数据（即冰盖形成后的天数）。研究涉及的湖泊分别为Allequash、Big Muskellunge、Crystal、Sparkling及Trout。Powers等（2017）曾利用该数据集估算了冬季外源化学物质向这些湖泊输入量的上下限。针对特定湖泊与冬季年份，研究人员计算了冰盖覆盖期内累积的地表水与地下水输入总量。本数据集针对每个湖泊，报告了多年观测得到的冬季水体输入量的均值、最大值与最小值，单位涵盖水体体积、占湖泊平均体积的百分比，以及每个冬季日的输入体积。采样频率为每个湖泊1次，同时报告多项汇总统计值（即均值、最小值与最大值）。研究站点总数为5个。
