abstract = "An analysis of the sporadic E layers (Es) in the Brazilian sector
has been carried out using data recorded by digital ionosondes
installed at S~ao Jose dos Campos (23.21S, 45.86W, dip angle:
-37.07, dip latitude: 20.69S), and Jata (17.9S, 51.7W, dip angle:
-25.16, dip latitude: 13.21S). In this study, statistical survey
of the types of Es layers at latitudes of the Equatorial
Ionization (EIA) and South Atlantic Magnetic (SAMA) anomalies were
obtained during the months that represent dierent seasonal periods
(April, June, September and December of 2016). The results
revealed the manifestation of four dierent types of Es layers (
at/low, cusp, high and slant), in which the at/low type was the
most frequent over both stations. In order to investigate the main
mechanisms acting to the generation of the Es layers, we used the
Ionospheric Model of the E Region (MIRE). Tidal winds parameters
estimated from Meteor Radar observations at Cachoeira Paulista
(22.42S, 45.0W, dip angle: -36.98, dip latitude: 20.63S) are used
as input to the MIRE model aiming to investigate tidal waves in
uence in the formation of these Es layers. The vertical proles of
ionospheric plasma density estimated by the MIRE are compared with
the electron density obtained using the blanketing frequency
parameter (fbEs) deduced from ionograms registered in the analyzed
regions. In general, the results show that the values computed by
the MIRE are in good agreement with the observational data for the
Es layers, in which it is conrmed that the Es layers formed near
both anomalies have a strong in uence of the wind shear
mechanism.",
