Air shower universality states that the electromagnetic part of hadron-induced
EAS can be completely described in terms of the primary energy and shower age.
In addition, simulations show that the muon part is well characterized by
an overall normalization which depends on the primary particle and hadronic
interaction model. We investigate the consequences of EAS universality
for ground ar

Using our new Monte Carlo code REAS2, geosynchrotron radio emission from
extensive air showers can now be calculated on the basis of individual high
quality CORSIKA-simulated showers. We present an analysis of the radio
emission properties predicted by REAS2, with particular focus on shower to
shower fluctuations and primary particle composition effects which can now
for the first time b

Since about one decade, air shower simulations based on the hadronic interaction
models QGSJET and SIBYLL predict very similar results for the main observables. For
instance, the mean depth of the shower maximum Xmax agrees within 5% between the
different models and are in relative good agreement with the measurements. However
the number of muons at ground differs substantially between th

Interpretation of EAS measurements strongly depends on detailed air shower
simulations. The uncertainty in the prediction of shower observables for different
primary particles and energies is currently dominated by differences between hadronic
interaction models.The new models QGSJET-II and EPOS, which reproduce all major
results of existing accelerator data (including detailed data of RHIC ex

The particle density in extensive air showers fluctuates at the ground level. These
fluctuations, at the scale of the scintillator detector size (several meters), lead
to the diversity of the individual detector responses. Therefore, small scale
fluctuations contribute to the error in the estimation of the primary energy by a
ground array. As a results of analysis of simulated full (unthinned)

Air shower simulation programs are used to reconstruct the energy in the UHECR
surface detectors. This reconstruction is based on the lateral distribution function
obtained in the experiment. It is also known that this function at core distance
greater than 1 km strongly depends on the low energy hadronic models used in the
simulation. There are discrepancies in the particle production
due to
