The Latin American Giant Observatory (LAGO) is an extensive network of water Cherenkovdetectors spread across Latin America, functioning as an astroparticle observatory. With its broadrange of altitudes and geomagnetic rigidity cut-offs, the primary focus of LAGO’s scientific pro-gram is to study space weather, climate phenomena, and high-energy astrophysical transients fromground level. To bolster these programs, the comprehensive simulation framework of ARTI andonedataSim was developed. This framework enables the calculation of the total secondary particleflux and the corresponding signals expected in various types of detectors operating anywhere inthe world. It also incorporates the effects of real-time atmospheric and geomagnetic conditions,both secular and disturbed. These tools harness the expanding computational capabilities of high-performance computing facilities and cloud-based computing environments. By integrating thesetools and infrastructures, we have managed to extend the total integration times of the backgroundflux and the energy range of atmospheric neutrons. In this contribution, we illustrate how this in-tricate simulation sequence aids in achieving LAGO’s scientific objectives. We also explore otherapplications, such as estimating the expected dose on board commercial flights, simulating themuon flux for muography studies, determining the distribution of neutrons in nuclear and medicalfacilities, and estimating the rate of errors produced by atmospheric neutrons in the upcominggeneration of exascale supercomputing centers worldwide.
