Sentinel 6 satellite should measure sea level millimeter accuracy

Kustenstadte could stand regularly under water, hurricanes and storm floods of crushing force and sinking island paradises in the sea: The rise of sea level is payable to the large threats that brings climate change with it. The global climate IPCC ames that at an unrestrained climate change, it could be more than a meter by the end of the century. That was then not only allowed to become a problem for the Maldives in the Indian Ocean, whose highest survey measures just a good two meters. The crisps of Europe are also in danger.

In order to measure and mapping the rise of sea level, scientists want to look for the oceans from space on the oceans – praiser than ever before. Sentinel-6 Michael, of course, scans 95 percent of the global sea surface within ten days – from a high of more than 1300 kilometers with accuracy under one millimeter.

Millimeter-based meng of the sea level

Earth observation satellites have been around for decades. "But Sentinel 6 has a new radar on board, with a higher precision that will make a more accurate increase in sea level", Says the director for earth observation programs at the European Space Agency ESA, Josef Aschbacher. As part of the European Earth Observation Program, the satellite is controlled by a new, state-of-the-art control center of the meteorological satellite agency in Europe, EUMETSAT, from Darmstadt, says the head of the program at the intestinal satellite specialists, Manfred Lergert.

For the realization of the spacecraft, many experts had to move to a strand. The mission is a cooperation of the ESA, the US space residence NASA, Eumetsat and the US weather and oceanography authority Noaa. The satellite is the first of two identical satellites that are shot into space. He is after the short dead Michael H. Of course, the former director of the NASA earth observation department, named.

The satellite should first be on 10. November from the Vandenberg Air Force Base in California to the All. Now the start is more delayed because the engines of the support rocket must be reviewed again. A new appointment was initially not fixed. The second, identical satellite should follow in fun and a half years. According to Ashbacher, Asschbacher, the stakeholders in the US and Europe each cost around 400 million euros.

The radar pulses of the satellite are sent out, reflected from the sea surface and reception. "Nobody can do anything with the data. This must be implemented in a high-priced removal residue", says lugert. "The exact location in orbit is the gross challenge of the mission." There had to be swelled and also atmospheric influence on distance quantities. On board two independent navigation systems for the location determination, and the satellite train is regularly measured with a laser. According to Aschbacher, in conjunction with other satellites, jerks can also be pulled on density and thickness of the ice. This is important, for example, the melting of the Gronlandeises has tripled since the 1990s.

Prazises lay picture

"We now get a global abbus every ten days, so a picture of how the situation is", says aschbacher. "The satellite supplies data that does not exist so exactly so far." As a state-of-the-art and highly praisar building block he will monitor the supervision of the planet of all. "There are certainly some 100 satellites currently in orbit and the earth well-woken up", says aschbacher. The Europeans are leading to this because the system is all cover – from science over weather forecasts to civil protection.

"But there is still a lot to do", Is Aschbacher sure. There is still parameters that you have to measure exactly. "One of the big challenges is the more accurate Meng of the greenhouse gas carbon dioxide." That is still not pracisse and flat enough. For the future, he wishes a satellite system that makes all these parameters. The data was then connected and coupled with artificial intelligence. This allows real predictions and simulations to make the system Earth, for example, how high the sea level increase at different temperature scenarios.
