This program is a toolkit to compute the evolution of particle densities that evolve as a cascade in the Earth’s atmosphere or other target media. Particles are represented by average densities on discrete energy bins. The results are differential energy spectra or total particle numbers. Various models/parameterizations for particle interactions and atmospheric density profiles are packaged with the code.
