A group of Brazilian researchers affiliated with the National Space Research Institute (INPE) is working to install a network comprised of magnetometers (instruments used to measure the intensity of a magnetic field) across South America.

The Embrace Magnetometer Network for South America (Embrace MagNet) involves joint efforts from other Latin American institutions with the aim of studying the specific characteristics of magnetic field disturbances over the continent and comparing their intensities with those occurring elsewhere in the world. The possible damage done by space weather to electronic appliances is also a primary subject.

Sao - Jose - Dos - Campos - Brazil

Located in Sao Jose dos Campos, Brazil, at the headquarters of the National Space Research Institute (Inpe), Embrace MagNet already has 13 magnetometers up and running. When the network is complete, it will consist of 24 magnetometers installed in 16 Brazilian states and Argentina, Chile and Uruguay.

Before Embrace MagNet, South American researchers depended on data from institutions in the U.S., Europe and Japan to study magnetic field disturbances over South America, according to INPE's head of space and atmospheric sciences, Clezio Marcos De Nardin.

Disturbances - Hemispheres - Publications - Literature - Show

"Magnetic disturbances aren't equivalent in the northern and southern hemispheres. Several publications in the scientific literature show that the aurora borealis and aurora australis aren't symmetrical, either," says the researcher. "Based on their data, when we heard that the magnetic field was disturbed, we had no idea if the disturbance had reached Brazil or whether we could assume the disturbance occurred in this sector," he adds.

The initiative was the subject of two articles penned by De Nardin and colleagues, recently published in Radio Science, a journal of the American Geophysical Union. The first article describes the network's scientific objectives and details its design, equipment, and installation and the treatment of the data it produces. In the second article , the authors disclose the initiative's first scientific...
