ARNO-RAIN: a comprehensive dataset of observed (20 years) and simulated (2000 years) sub-hourly precipitation series for 70 rain gauges

ARNO-RAIN, a benchmark dataset of observed and simulated precipitation time series for 70 rain gauges in the Arno River basin (central Italy), is here presented. For each station, the dataset includes: 20 years of continuous 15-minute and daily rainfall observations; a 2000-year synthetic daily rainfall series generated using the CoSMoS-2s stochastic model; a corresponding 2000-year synthetic 15-minute series obtained by multifractal canonical disaggregation calibrated against observed intensity–duration–frequency curves.本文介绍了ARNO-RAIN基准数据集（benchmark dataset），该数据集涵盖意大利中部阿诺河流域70个雨量站的实测与模拟降水时间序列。针对每个测站，该数据集包含如下内容： - 20年连续的15分钟分辨率与日尺度降水观测序列； - 采用CoSMoS-2s随机模型生成的2000年合成日降水序列； - 通过基于实测强度-历时-频率曲线（intensity–duration–frequency curves）校准的多重分形正则分解（multifractal canonical disaggregation）得到的对应2000年合成15分钟降水序列。
