The main purpose of this project is study day-to-day variability of the dynamics upper atmosphere (mesosphere and thermosphere) and ionosphere electrodynamics, during the solar cycle 24, at low-latitudes and equatorial region, Brazilian sector, using a network of four observatories. Also, complementary data from other sectors and satellite data will be used in this project. The following topics will be study: a) Mesosphere-thermosphere, thermosphere-ionosphere, magnetosphere-thermosphere-ionosphere coupling during geomagnetic quiet and disturbed periods, b) Gravity waves and planetary waves propagations at mesosphere and thermosphere, c) Travelling Ionospheric Disturbances (TIDs) and Meso-Scale Travelling Ionospheric Disturbances (MSTIDs) propagation at ionospheric heights, d) Equatorial Large scale and bottom side ionospheric irregularities generation, evolution and propagation studies, e) Ionospheric F3 layer studies at equatorial and low-latitude regions; f) Ionospheric and upper atmospheric signatures of sudden stratospheric warming at equatorial and lo-latitude region, g) Study of the equatorial eletroject and counter eletroject in the American sector.
