abstract = "Based on the data obtained from a network of GPS L1 band receivers
deployed in Brazil, are presented here the characteristics of the
400 m ionospheric irregularities during magnetically quiet and
disturbed conditions. The network is composed of 12 GPS
scintillation monitors and covers the latitudinal region from the
magnetic equator up to the southern crest of the Equatorial
Ionization Anomaly (EIA), which is characterized by large
horizontal gradients in the electron density distribution. Some
results on equatorial spread-F statistics obtained from digisonde
data over Cachoeira Paulista (22.41o S, 45o W, dip latitude 14.89o
S) and from ionosonde data over Tucum{\'a}n (64.5o W, 27o S, dip
latitude 13.71o S) are also used in this work to complement the
results from GPS network. The effects of local time, season,
latitude, longitude, background ionization, solar cycle and
magnetic activity on the ionospheric irregularities are presented.
The ionospheric irregularity zonal velocities determined by
magnetically east-west spaced GPS receivers are also presented.
The influence of the ionospheric irregularities on GPS based
navigational systems is discussed. These observations,
complemented by computational simulations, may improve our
understanding of the factors responsible for the generation,
growth and dynamics of the equatorial F-region plasma
irregularities.",
