Seawater continues to rise, NASA investigates unusual Earth symptoms from …

NEW YORK – Recent research shows that sea levels continue to rise and the result is that more coastal areas are submerged. This prompted the NASA space agency of the United States and the European ISS to pilot a new satellite to monitor global sea level rise which will be launched on Saturday (11/21/2020).

This satellite will measure sea level height, wave height and wind speed, using radar techniques.

The satellite’s most powerful device, the Poseidon-4 radar altimeter, is named after the Greek sea god who wielded a trident. This instrument will measure the time it takes for radar signals to bounce off the sea surface and return to the satellite.
A recent study cites a growing search for ice sheets in Greenland and Antarctica.

The study, published in Nature Climate Change, compares the mass balance results of the ice sheet from satellite observations with climate model projections. (Read also: Van Gaal Honest, Claims Only Now Like Watching Italy Playing)

Since systematic monitoring of the ice sheet began in the early 1990s, Greenland and Antarctica have lost 6.4 trillion tons of ice between 1992 and 2017. This event pushed sea levels to rise. of 17.8 mm.

If this speed continues, the ice sheet is expected to raise the sea surface by an additional 17 cm and result in more submerged coastal areas.

The study’s lead author and climate researcher at the Center for Polar Observation and Modeling at the University of Leeds, Tom Slater, said satellites were the only way to regularly monitor this vast and remote area.

So satellites are very important in providing the measurements we can use to validate our ice sheet models.

“Satellite observations not only tell us how much ice is being lost, they also help us identify and understand which parts of Antarctica and Greenland are losing ice and through which processes – both are critical in helping us improve our ice sheet model. “he said. Official European Space Agency (ESA).

ESA’s Marcus Engdahl added that satellite observations show that the ice sheet reacts very quickly environmental change.

“It is very important for scientists to have access to data from future satellite missions that they can observe arctic regions, for example, the mission of the upcoming high priority Copernicus candidates CRISTAL, ROSE-L and CIMR,” he said.
