资源简介:
This resource provides water quality data for Winter et al. (2020) from the Selke catchment (456 km², Germany), a sub-catchment of the Bode catchment, which is part of the network of TERrestrial ENvironmental Observatories (TERENO). Within the Selke catchment, we consider three nested sub-catchments that are delineated by the following gauging stations: i) Silberhütte (SH) , ii) Meisdorf (MEIS) and iii) Hausneindorf (HAUS). More specifically, this resource provides the following datasets:
1) Annual and seasonal averages of flow-normalized (FN) and non-FN nitrate concentrations (C in mg/L), loads (L in kg/d) and CQ-slopes (ß)between 1983 - 2016 for all three nested sub-catchments, calculated via Weighted Regression on Time, Discharge and Season (WRTDS, Hirsch et al. 2010).
2) Annual nitrogen (N) input data for all three sub-catchments (in kg/ ha * a) between 1950 - 2015. This N-input data is the sum of N-input from agricultural areas, N-input from non-agricultural areas (atm. deposition and biological fixation) and to a minor part from wastewater treatment plants (WWTPs).
3) A table of event characteristics from high-frequency measurements between 2013 - 2016 in Silberhütte and between 2010 - 2016 in Meinsdorf and Hausneindorf (15 min resolution, Qmax in mm and Cmax in mg/L, R2 is the coefficient of determination).
本数据集为Winter等人2020年的研究提供德国塞尔克流域(Selke catchment,面积456 km²)的水质数据,该流域是博德流域(Bode catchment)的子流域,而博德流域属于陆地环境观测网络(TERrestrial ENvironmental Observatories, TERENO)。
在塞尔克流域内,我们选取了三个嵌套子流域,分别由以下水文监测站划定:i) 西尔伯胡特站(Silberhütte, SH)、ii) 迈斯多夫站(Meisdorf, MEIS)以及iii) 豪斯奈因多夫站(Hausneindorf, HAUS)。
本数据集包含以下三类数据:
1. 1983年至2016年间,三个嵌套子流域的流量归一化(flow-normalized, FN)与非流量归一化硝酸盐浓度(单位:mg/L)、负荷量(单位:kg/d)以及CQ斜率(ß)的年际与季节均值,该数据通过时间、流量与季节加权回归法(Weighted Regression on Time, Discharge and Season, WRTDS, Hirsch et al. 2010)计算得到。
2. 1950年至2015年间,三个子流域的年度氮素(N)输入数据(单位:kg/ha·a)。该氮素输入量涵盖农业区氮输入、非农业区氮输入(大气沉降与生物固氮),以及少量来自污水处理厂(wastewater treatment plants, WWTPs)的氮输入。
3. 2013年至2016年西尔伯胡特站、2010年至2016年迈恩斯多夫站与豪斯奈因多夫站的高频监测事件特征表(采样分辨率为15分钟,包含最大流量Qmax 单位mm、最大浓度Cmax 单位mg/L,以及决定系数R²)。
