Abstract The Earth atmosphere is constantly reached by cosmic rays, i.e. energetic and subatomic particles coming from all directions from space. A muon telescope is housed at the Legnaro National Laboratories (LNL) of the Italian Istituto Nazionale di Fisica Nucleare (INFN). This instrument is used to introduce students to research activities in the field of particle physics. In particular, during the International Cosmic Day (ICD) and in following Pathways for Transversal Competences and Orientation (PCTO) activities, students can perform measurements and data analysis of the muon flux reaching the Earth’s surface. It is well known that this flux is affected by the atmospheric condition in which the measurement is done. In this contribution, we present the long-term investigation performed with high school and bachelor students in Physics at the University of Padova, of the anticorrelation between muon counts and atmospheric pressure as measured with the muon telescope in LNL using the data collected from 2022 to 2024. The results of our analysis confirm the stability of this anticorrelation during data collection. Further analyses allow us to investigate also the time variations of these correlations in different months, indicating a possible effect due to summer and winter conditions and finally with the recent high solar activity. Currently we are investigating also the impact of other atmospheric-related correlations, such as temperature and humidity.
