Scientific paper

The first distributed observatory dedicated to study the low-latitude ionosphere and upper atmosphere has being designed and is now being implemented in South America. Description of its three basic sensors (GPS receivers, magnetometers and dynasondes) will be provided. These 3 instruments complement each other and jointly provide a multi-dimensional view of the low-latitude space weather in South America. The initial LISN project will connect 70+ GPS receivers, 5 sounders and several magnetometers, all placed in South America west of the 55° W meridian. We also present a picture of the assimilation code that will be used to ingest the instrumental observables and define atmospheric and ionospheric state parameters. It is expected that the distributed observatory will provide new, time continuous, and spatially extended observations of the background ionosphere, its motion, and the embedded structures. It is expected that several science efforts, such as studies of the low-latitude electrodynamics, space weather-related onset of equatorial spread F, and transit of atmospheric gravity waves throughout the LISN field of view will be invigorated by the availability of a new data set that will contain a unique spatial resolution and unprecedented coverage.
