In the last years, several models and simulations calculating the radio
emission from cosmic ray air showers have been developed. However, a number of
those made conflicting predictions on the pulse shapes and the amplitudes of
the radio signal. In the scope of this paper, we discuss a detailed comparison
of two independent and complementary theoretical approaches, namely MGMR and
REAS3. Furthermore, we study the influence of the underlying air shower models
on the predicted pulse shapes and amplitudes and show that remaining
discrepancies between MGMR and REAS3 are mostly determined by the air shower
models. With this general agreement, a breakthrough in the understanding of the
modelling of radio emission from air showers has been achieved.
