Description
The HelMod (heliospheric modulation) model was developed to account for the transport of Galactic Cosmic Ray through the heliosphere.
At present, the model is also used to forecast Ions Cosmic Rays Intensities in the current and coming solar cycles.
The latter procedure include a fine tuning on the current solar cycle.
HelMod is a 2-D Monte Carlo and includes a general description of symmetric and antisymmetric parts of diffusion
tensor, thus properly treating particle drift effects as well as convection due to solar wind and adiabatic energy losses.
Particular care was dedicated to describe polar regions of the heliosphere.
The HelMod tool is available for public use as a set of Online Calculators at www.helmod.org.
The Model accounts for 1) all the data observed by ulysses mission outside the
ecliptic plane at several distances from the Earth (KET measurements) and 2) the spectra observed in deep space during high
and low solar activity periods, including data from SREM detectors (onboard of ROSETTA, PLANCK, Integral, etc).
We present the latest results of the model reproducing the measured cosmic rays spectra at Earth and in deep space.
