Historic reconstructions of daily groundwater levels for eight boreholes in Burkina Faso (NERC Grant NE/M008827/1)

This dataset consists of reconstructions of daily groundwater levels for eight boreholes in Burkina Faso. Data for each borehole is provided in an individual csv file, with reconstructed groundwater level time series reported in metres above sea level (GWL, mASL). The groundwater level reconstructions were derived in 2019 as a part of the BRAVE project (NE/M008827/1 and NE/M008983/1) to develop an improved understanding of temporal variability in groundwater levels in sub-Saharan Africa. The reconstructions were derived using the lumped conceptual groundwater model AquiMod. Observed groundwater level time series for the eight boreholes were modelled using AquiMod, and the calibrated models were used with historic precipitation and potential evapotranspiration data to derive the reconstructions. The length of the time series of reconstructed groundwater levels varies between the boreholes due to differences in the length of the precipitation time series used to derive the reconstructions. Full details of this dataset are reported by Ascott et al. (2020).

本数据集包含布基纳法索8个钻孔的逐日地下水位重建序列。每个钻孔对应一份独立的CSV文件，其中重建的地下水位时间序列以海拔米数为单位，记作地下水位（Groundwater Level, GWL, mASL）。本次地下水位重建工作于2019年开展，作为BRAVE项目（资助编号：NE/M008827/1与NE/M008983/1）的组成部分，旨在加深对撒哈拉以南非洲地区地下水位时间变异性的认知。重建过程采用集总式概念性地下水位模型AquiMod完成：研究人员利用该模型对8个钻孔的实测地下水位时间序列进行建模，并将校准后的模型结合历史降水与潜在蒸散发数据，生成目标重建序列。由于各重建序列所用降水时间序列的长度存在差异，不同钻孔的地下水位重建序列时长各不相同。本数据集的完整细节详见Ascott等人（2020）的研究成果：Ascott, M.J., Macdonald, D.M.J., Black, E., Verhoef, A., Nakohoun, P., Tirogo, J., Sandwidi, W.J.P., Bliefernicht, J., Sorensen, J.P.R., Bossa, A.Y., 2020. 实地观测与集总参数模型重建揭示撒哈拉以南非洲地下水位年内至多年代际变异性. 《水资源研究（Water Resour.
