Multistation Sensor Time Series Dataset (chunk 2 of 2)

This dataset comprises raw time series data collected from five monitoring stations (station_001 through station_005). Each station file is stored in NumPy format (.npy) as a 1000×78 array of float32 values. Rows correspond to successive time steps (n=1000), and columns correspond to 78 sensor channels measuring environmental variables. Recorded values range approximately from –26.7 to 17.6 with a mean near zero. The data are provided for use in descriptive statistics, anomaly detection, and modeling within the environmental sensor network domain.本数据集包含从5个监测站点（station_001至station_005）采集的原始时序数据。 各站点的数据文件均以NumPy格式（.npy）存储为1000×78的32位浮点型（float32）数组。 数组的行对应连续的时间步（共计1000个时间步），列对应78个用于测量环境变量的传感器通道。 记录数值的取值范围大致为–26.7至17.6，均值接近0。 本数据集可供环境传感器网络领域内的描述性统计、异常检测及建模相关研究使用。
