abstract = "This work presents new results about sporadic E-layers (Es layers)
using GPS (global positioning system) radio occultation (RO)
measurements obtained from the FORMOSAT-3/COSMIC satellites and
digisonde data. The RO profiles are used to study the Es layer
occurrence as well as its intensity of the signal-to-noise ratio
(SNR) of the 50 Hz GPS L1 signal. The methodology was applied to
identify the Es layer on RO measurements over Cachoeira Paulista,
a low-latitude station in the Brazilian region, in which the Es
layer development is not driven tidal winds only as it is at
middle latitudes. The coincident events were analyzed using the RO
technique and ionosonde observations during the year 2014 to 2016.
We used the electron density obtained using the blanketing
frequency parameter (fbEs) and the Es layer height (h'Es) acquired
from the ionograms to validate the satellite measurements. The
comparative results show that the Es layer characteristics
extracted from the RO measurements are in good agreement with the
Es layer parameters from the digisonde.",
