  LAGO, the Latin American Giant Observatory, is an extended cosmic ray
observatory, consisting of a wide network of water Cherenkov detectors located
in 10 countries. With different altitudes and geomagnetic rigidity cutoffs,
their geographic distribution, combined with the new electronics for control,
atmospheric sensing and data acquisition, allows the realisation of diverse
astrophysics studies at a regional scale. It is an observatory designed, built
and operated by the LAGO Collaboration, a non-centralised alliance of 30
institutions from 11 countries.
  While LAGO has access to different computational frameworks, it lacks
standardised computational mechanisms to fully grasp its cooperative approach.
The European Commission is fostering initiatives aligned to LAGO objectives,
especially to enable Open Science and its long-term sustainability. This work
introduces the adaptation of LAGO to this paradigm within the EOSC-Synergy
project, focusing on the simulations of the expected astrophysical signatures
at detectors deployed at the LAGO sites around the World.
