Multivariate time-series sensor measurements from five monitoring stations (chunk 1 of 2)

This dataset comprises time-series sensor measurements collected at five distinct monitoring stations. Each of the five NumPy (.npy) files contains a 1000×78 float32 array: rows correspond to sequential time points and columns represent different measurement variables. Observations span a value range of approximately -26.7 to +17.6 units, with a mean near zero. The data are well-suited for descriptive statistical analysis, anomaly detection, and development of time-series modeling methods within environmental monitoring or related scientific fields.
