Abstract. A survey of the data on measured particle fluxes and the rate of
ionization in the atmosphere is presented. Measurements as a function
of altitude, time and cut-off rigidity are compared with simulations
of particle production from cosmic rays. The simulations generally
give a reasonable representation of the data. However, some
discrepancies are found. The solar modulation of the particle
fluxes is measured
and found to be a factor 2.7 ± 0.8 greater than that observed
for muons alone near sea level.
