Pi2 pulsation event annotation time-series dataset

This dataset is used for Pi2 pulsation identification. The raw data is the 1Hz sampling H-component data of magnetic fluxgate magnetometer instrument of meridian project, (data source: https://data.meridianproject.ac.cn/), select time range for the 2011-2021. The data were labeled according to the method described in "Identification Model of Pi2 Pulsation Based on One-dimensional residual Convolutional neural Network".
