A European satellite will now be able to monitor the environmental changes and can ‘see’ migrants influx reaching across the European borders.

Sentinel-3A was launched into orbit on Tuesday by a Russian rocket. It is a third add-on in European Union’s Copernicus program, one of the highest sophisticated Earth observation system ever launched, says The European Space Agency.

The satellite is “one of more than a dozen satellites”.  It will assist two other satellite already moving in orbit to boost the efforts in the measurement of sea and surface temperatures.

Sentinel 3A will be able to notify about the upcoming droughts and the activities of people intending to cross the Mediterranean to Europe, says Josef Aschbacher, who oversees the Earth observation program.

“(This) will warn politicians that the harvest in a particular country will be lower and this can be a source of migration.” Aschbacher said in a report by ABC News.

The satellite will examine the entire planet in just over a day and can provide detailed information to scientists  about the environmental changes in almost real time. It will help measure sea temperatures to track the impact of climate change and will boost the short-term weather forecasts.

With the satellite in space and reporting on climate changes, leaders can be easily notified by any mass migration that is usually happens because of negative climate change impact.

On June 23, 2015, The ESA launched – Sentinel-2A; it possessed high-resolution optical imaging capability.

“Sentinel-2 is the second satellite of a constellation of 20 satellites which will scrutinise planet Earth. It will  improve the ability of Copernicus to provide European citizens with the most comprehensive data for environmental and security applications available anywhere in the world,” noted ESA Director General Jean-Jacques Ordain in a report file by ESA.

Unprecedented flow of migrants and mass drownings at sea are major concerns of European countries. The Copernicus system can also track people mustering to cross the Mediterranean to Europe. Although, other satellites or drones with greater resolution would be required to speed up the process.
