Good Practice Guide for the simulation and estimation of particle fluxes during minimum solar activity, maximum solar activity and the recent Solar Energetic Particle Events

This Good Practice Guide intends to summarize the best way to estimate the space particle fluxes and their
interactions with the atmosphere. It provides guidance for the analysis of space radiation fluxes using satellite
measurements and for the simulations of their interactions with the terrestrial atmosphere using the AtRIS
code. It also provides the most recent results obtained at BIRA-IASB for different solar eruption events and
geomagnetic storms, especially during solar cycle 25 which has its maximum in 2025. This guide written in the
framework of the EURAMET Biosphere project is made available on the project’s website www.eurametbiosphere.
eu and promoted in the project’s workshops/training events so that users in space physics, radiation
and atmospheric communities can easily access these documents for reference and to implement the methods
for estimations of spatial energetic fluxes of particles and for atmospheric investigations developed in the
project.
