Magnetic Field: Geophysicist Dhananjay Ravat Developed High-Resolution Map

Dramatic new information regarding the Earth's magnetic field is being revealed by a geophysicist of the University of Kentucky. He is a part of the international team of scientists working on the Earth's magnetic field. A high-resolution map of the magnetic field of the earth has been developed by the geophysicist.

According to Phys.org, Dhananjay Ravat, a geophysicist and professor in the UK Departments of Earth and Environmental Sciences and Physics and Astronomy has involved with a team of international scientists which led to the development of a high-resolution map of earth's magnetic field. Ravat worked on geophysical data which was collected from various space missions around the earth, mars, and moon.

Before two years the leader of Swarm Satellite Constellation and Research Facility of the European Space Agency (ESA) asked Ravat to join with their team of scientists for creating a map of Earth's magnetic field. This led Ravat to join the team of scientists and develop the high-resolution map.

The University of Kentucky reported that European Space Agency launched three spacecraft. These spacecraft are known as Swarm Satellites. Swarm Satellites were launched into the orbit of planet Earth in the year 2013 for studying planet's lithosphere magnetic field. There was no clear conception about the map of the magnetic field of the earth but due to the Swarm Mission, now scientists have a better understanding.

The magnetic field of the earth is responsible for the deflections in the dangerous solar winds and the impacts on earth's climate and rotations. The map not only gives a detailed understanding of the magnetic field but also reveals the polarity flips of Earth in great detail. Geophysicist Ravat said, "Magnetic fields have been measured in space by satellites for the last 50 years, but it is the measurement of magnetic 'gradients' from the three Swarm satellites and data from a previous German CHAMP satellite that makes this the highest resolution possible." It is expected that the map will change the present understanding of Earth's crust and its mineral resources.
