Seawater Continues to Rise, NASA Investigates Unusual Symptoms of Earth from …

NEW YORK – Recent research mentions surfacethe sea continues to rise and resulting in more submerged coastal areas. This prompted the space agency to the United States NASA and Europe’s ISS to fly a new satellite to track world sea level rise to 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 radar altimeter Poseidon-4, is named after the Greek sea god who wielded a trident. This instrument will measure how long it takes for radar signals to bounce off the surface of the sea and return to the satellite.
A recent study cites an increasing search for ice sheets in Greenland and Antarctica.

The study, published in Nature Climate Change, compares the results of the mass balance of the ice sheet from satellite observations with projections from climate models. (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 lost 6.4 trillion tonnes of ice between 1992 and 2017. This event pushed global sea levels up 17.8 millimeters.

If this rate continues, the ice layer is expected to raise the sea surface further 17 cm and result in more submerged coastal areas.

Lead author of the study and climate researcher at the Center for Polar Observation and Modeling at the University of Leeds, Tom Slater, says satellites are their only way to routinely monitor these large, remote areas.

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 lost, but also help us identify and understand which parts of Antarctica and Greenland are losing ice and through what processes – both of which are key 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 to environmental change.

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