Equatorial Electrojet model developed by IIG

The equatorial electrojet (EEJ) is an intense current jet flowing in the upper atmosphere around 100 km. This is a unique phenomenon that occurs at only a few kilometers in height (e.g., 105 – 110 km) and with a horizontal (North-South) width of a few hundred kilometers (e.g., ~600 km)... more

Weakened control of crustal magnetic fields on the...

Mars is a planet which does not possess a global magnetic field. But it has weak local crustal magnetic fields in its southern hemisphere. Using nearly 8 years of MAVEN (Mars Atmosphere and Volatile EvolutioN) satellite in situ data, IIG scientists investigated how the crustal magnetic fields... more
