abstract = "We have being studying the zonal and vertical E region electric
field components inferred from the Doppler shifts of type 2 echoes
(gradient drift irregularities) detected with the 50 MHz
backscatter coherent radar set at S{\~a}o Luis, Brazil (SLZ,
2.3°S, 44.2°W) during the solar cycle 24. In this report we
present the dependence of the vertical and zonal components of
this electric field with the solar activity, based on the solar
flux F10.7. For this study we consider the geomagnetically quiet
days only (Kp \≤ 3+ ). A magnetic field-aligned-integrated
conductivity model was developed for proving the conductivities,
using the IRI-2007, the MISIS-2000, and the IGRF-11 models as
input parameters for ionosphere, neutral atmosphere, and Earth
magnetic field, respectively. The ion-neutron collision
frequencies of all the species are combined through the momentum
transfer collision frequency equation. The mean zonal component of
the electric field, which normally ranged from 0.19 to 0.35 mV/m
between the 8 and 18 h (LT) in the Brazilian sector, show a small
dependency with the solar activity. Whereas the mean vertical
component of the electric field, which normally ranges from 4.65
to 10.12 mV/m, highlights the more pronounced dependency of the
solar flux.",
