Abstract: The Muon Telescope at Siziwang Station in Inner Mongolia is used to detect the secondary cosmic ray muons reaching the ground. Muon signals generated by the telescope’s 48 detection units undergo processing steps including amplification, discrimination, shaping, and directional coincidence calculation to produce raw muon counts. These counts are further refined through atmospheric pressure correction calculations to form a dataset of corrected muon counts in 15 directions, with a temporal resolution of 1 hour. The muon data can sensitively reflect diurnal variations, long-term variations of cosmic rays, and short-term Forbush decrease perturbations induced by coronal mass ejections. Spanning from May 2023 to April 2025, this dataset covers the high-activity phase of the 25th solar activity cycle. It provides valuable data resources for research on solar eruptions, their interplanetary disturbance propagation, and geomagnetic response processes, while also supporting space weather early warning efforts.
