The observatory is also meant to address Long Distance Correlation (LDC) phenomena: the network is deployed over a broad area covering 10 degrees in latitude and 11 in longitude. An overview of a set of preliminary results is given, extending from the study of local muon flux dependance on solar activity to the investigation of the upward-going component of muon flux traversing the EEE stations; from the search for anisotropies at the sub-TeV scale to the hints for observations of km-scale Extensive Air Shower (EAS).

The muon telescope of the EEE Project is made by 3 Multigap Resistive Plate Chambers (MRPC). The unconventional working sites are a unique test field for checking the robustness and the low-ageing features of the MRPC technology for particle tracking and timing purposes. The MRPCs are fluxed with a standard mixture (98% C2H2F4 - 2% SF6) of greenhouse gases (GHG) phasing out of production. The EEE Collaboration is currently studying alternative mixtures environmentally and economically sustainable. The EEE Collaboration actions to reduce the Global Warming Potential (GWP) in the MRPC array of the EEE experiment are progressing.

A station of the network, called "telescope", consists of three superimposed Multi-gap Resistive Plate Chambers (MRPCs), each one covering a surface of about 1.5 2 , used with the same technology as the time-of-flight detector of the ALICE experiment at CERN-LHC. Data are collected and sent in real time to the INFN-CNAF computer center for reconstruction and analysis. The large area covered by the network, ranging from Southern Italy up to the CERN laboratories, was achieved with the decision to install the detectors inside high schools, involving students and teachers in a modern experiment within a unique program. This very coexistence of scientific activity and outreach represents the uniqueness of the EEE Project. The outreach programme is articulated in several initiatives, each encoding the different aspects of the research activity normally expected in a highenergy physics experiment. Students are involved in detector construction at CERN, installation in school, and in the commissioning of the station when data taking starts. Once the detector reaches a steady working regime, students are requested to monitor on a daily basis the performance of the telescope and report any failure. In parallel to the hardware-related operations, students learn how to perform the analysis of EEE data under the supervision of their teachers and of the EEE researchers, supporting the scientific output of the experiment. Every month students report progress and issues in a dedicated online meeting open to all schools and to the EEE researchers. Beside this monthly appointment, in the pre-COVID era an in-person meeting was taking place twice per year, hosted by the Ettore Majorana Foundation and Centre for Scientific Culture in Erice or by a school or institution involved in the project. During a three-day, students attend masterclasses and take part in measurement campaigns, disseminating their results by submitting contributions to important outreach-oriented journals (such as the Italian Giornale di Fisica).

The detector, contained in a trolley, is transportable and simple enough to be used by high-school students. The sophisticated data acquisition system is based on advanced DAQ technology and thanks to a simple interface is suitable for non-expert users. The detector is capable of measuring an integrated cosmic muon rate of 1-2 Hz with a precision (statistical and systematic) of a few percent in few hours of data taking. It can be used to detect variations induced by the solar activity, to determine the rate dependence on the geographical location (altitude and latitude) and to measure the cosmic muon rate attenuation due to surrounding high-density shielding such as rocks or concrete walls.

The EEE network is composed, so far, of 53 telescopes, each made of three MRPC detectors; it is organized in clusters and single telescope stations distributed all over the Italian territory and installed in High Schools, covering an area larger than 3 × 10 5 km 2. The study of Extensive Air Showers (EAS), that is one of the goal of the project, requires excellent performance in terms of time and spatial resolution, efficiency, tracking capability and long term stability. The data from two recent coordinated data taking periods, named Run 2 and Run 3, have been used to measure these quantities and the results are here reported, together with a comparison with expectations and with the results from a beam test performed in 2006 at CERN.

Besides the many research activities concerned with extensive air shower detection, long distance correlation studies and additional physics results obtained during the last decade, the EEE project is extensively employed for educational and outreach activities, constituting a unique opportunity to promote a fruitful and close collaboration between students, high-school teachers and researchers. The involvement is at all levels, from the construction of the chambers during short stages at CERN over the past 15 years, with the participation of several hundred high-school students and teachers, to the installation, monitoring and data taking with the telescopes by highschool teams, to masterclasses, physics lectures, data analysis sessions and joint discussions on the results and their interpretation. Recent developments of the EEE network led to the installation and use of additional detectors in the Arctic region and on board of sailing ships, to measure the cosmic ray flux over large latitude intervals. Periodical remote and in presence (pre-Covid era) meetings allowed in these years a large participation (several thousand people) from the high-school community to the EEE activities. National and local outreach initiatives in cosmic ray physics are also carried out around Italy by the EEE network, as a contribution to the dissemination of science among young people.

A latitude range well above the Arctic Circle was explored on board of a sailboat, up to the unprecedented northernmost value of $$82^{\circ }07^{\prime }$$ 82 ∘ 07 ′ N. In this paper a description of the experimental set-up is reported, then the procedures for calibration and data analysis are described in detail. The results show that the rate measured in this latitude range stays constant within a novel accuracy of $$\pm 1$$ ± 1 %.

The EEE network consists of 60 telescopes distributed over all the Italian territory; each telescope is made of three MRPCs and allows to reconstruct the trajectory of cosmic muons with high efficiency and optimal angular resolution. A distinctive feature of the EEE network is that almost all telescopes are housed in High Schools and managed by groups of students and teachers, who previously took care of their construction at CERN. This peculiarity is a big plus for the experiment, which combines the scientific relevance of its objectives with effective outreach activities. The unconventional location of the detectors, mainly in standard classrooms of school buildings, with heterogeneous maintenance conditions and without controlled temperature and dedicated power lines, is a unique test fi...
