We present a methodology to simulate the impact of the atmospheric models in the background particle flux on ground detectors using the Global Data Assimilation System. The methodology was within the ARTI simulation framework developed by the Latin American Giant Observatory Collaboration. The ground level secondary flux simulations were performed with a tropical climate at the city of Bucaramanga, Colombia. To validate our methodology, we built monthly profiles over Malargüe between 2006 and 2011, comparing the maximum atmospheric depth, X<sub>max</sub>, with those calculated with the Auger atmospheric option in CORSIKA. The results show significant differences between the predefined CORSIKA atmospheres and their corresponding Global Data Assimilation System atmospheric profiles.

We present the Colombo-Argentinian Muography Program for studying inland Latin-American volcanoes. It describes the implementation of a simulation framework covering various factors with different spatial and time scales: the geomagnetic effects at a particular geographic point, the development of extensive air showers in the atmosphere, the propagation through the scanned structure and the detector response. Next, we sketch the criteria adopted for designing, building, and commissioning MuTe: a hybrid Muon Telescope based on a composite detection technique. It combines a hodoscope for particle tracking and a water Cherenkov detector to enhance the muon-to-background-signal separation due to extensive air showers' soft and multiple-particle components. MuTe also discriminates inverse-trajectory and lowmomentum muons by using a picosecond Time-of-Flight system. We also characterise the instrument's structural -mechanical and thermal-behaviour, discussing preliminary results from the background composition and the telescope-health monitoring variables. Finally, we discuss the implementations of an optimisation algorithm to improve the volcano internal density distribution estimation and machine learning techniques for background rejection.

The Space Weather program of the Latin American Giant Observatory (LAGO) Collaboration was designed to study the variation of the flux of atmospheric secondary particles at ground level produced during the interaction of cosmic rays with the air. This work complements and expands the inference capabilities of the LAGO detection network to identify the influence of solar activity on the particle flux, at places having different geomagnetic rigidity cut‐offs and atmospheric depths. This program is developed through a series of Monte Carlo sequential simulations to compute the intensity spectrum of the various components of the radiation field on the ground. A key feature of these calculations is that we performed detailed radiation transport computations as a function of incident direction, time, altitude, and latitude and longitude. Magnetic rigidity calculations and corrections for geomagnetic field activity are established by using the MAGNETOCOSMICS code, and the estimation of the flux of secondaries at ground level is implemented by using the CORSIKA code; thus, we can examine the local peculiarities in the penumbral regions with a more realistic description of the atmospheric and geomagnetic response in these complex regions of the rigidity space. As an example of our calculation scheme, we report some result on the flux at ground level for two LAGO locations: Bucaramanga, Colombia, and San Carlos de Bariloche, Argentina, for the geomagnetically active period of May 2005.
