For about 24 000 river basins across Europe, we provide a continuous representation of the streamflow regime in terms of empirical flow-duration curves (FDCs), which are key signatures of the hydrological behaviour of a catchment and are widely used for supporting decisions on water resource management as well as for assessing hydrologic change. In this study, FDCs are estimated by means of the geostatistical procedure termed total negative deviation top-kriging (TNDTK), starting from the empirical FDCs made available by the Joint Research Centre of the European Commission (DG-JRC) for about 3000 discharge measurement stations across Europe. Consistent with previous studies, TNDTK is shown to provide high accuracy for the entire study area, even with different degrees of reliability, which varies significantly over the study area. In order to provide this kind of information site by site, together with the estimated FDCs, for each catchment we provide indicators of the accuracy and reliability of the performed large-scale geostatistical prediction. The dataset is freely available at the PANGAEA open-access library (Data Publisher for Earth & Environmental Science) at https://doi.org/10.1594/PANGAEA.938975 (Persiano et al., 2021b).

欧洲的流数据可用性：插值流持续时间曲线的详细数据集

对于欧洲约 24 000 个河流流域，我们根据经验流量持续时间曲线 (FDC) 提供了河流流态的连续表示，这是流域水文行为的关键特征，广泛用于支持水资源决策资源管理以及评估水文变化。在本研究中，FDC 是通过称为总负偏差顶克里金法 (TNDTK) 的地质统计程序估算的，从欧洲委员会联合研究中心 (DG-JRC) 提供的经验 FDC 开始，用于大约 3000 次排放测量遍布欧洲的车站。与以前的研究一致，TNDTK 被证明可以为整个研究区域提供高精度，即使具有不同程度的可靠性，这在研究区域内差异很大。为了逐个站点提供这种信息，连同估计的 FDC，我们为每个流域提供了所执行的大规模地质统计预测的准确性和可靠性的指标。该数据集可在 PANGEA 开放存取图书馆（地球与环境科学数据出版商）免费获得，网址为 https://doi.org/10.1594/PANGAEA.938975（Persiano 等人，2021b）。
