This in turn will allow one to recognise how the melting of different glaciers will affect different cities.
As most of the earth's freshwater is stored in glaciers and ice sheets, their melting owing to global warming is a major factor in rising sea level.
Rio de Janeiro, New York City, and Miami would all be severely impacted by melting glacier systems in Greenland.
NASA's new simulation is the most recent to visualize these changes, but it takes things a step further by breaking down which cities will be effected by various sources of melting ice.
Past NASA inquire about has said that if Antarctic ice in the western part of the mainland were to soften, the world's ocean levels would rise four feet over the globe, yet the Eastern Seaboard of the USA would see ascents of more than triple that gauge.
This causes patterns that vary across the globe.
The study is based on findings by the scientists at NASA'S Jet Propulsion Laboratory from forecasting tool and gradient fingerprint mapping (GFM).
'We exploit an advanced mathematical property of adjoint systems and determine the exact gradient of sea-level fingerprints with respect to local variations in the ice thickness of all of the world's ice drainage systems, ' the researchers explain in the study published to Science Advances.
"By exhaustively mapping these fingerprint gradients, we form a new diagnosis tool, henceforth referred to as gradient fingerprint mapping (GFM), that readily allows for improved assessments of future coastal inundation or emergence", the study said.
Earlier this month, a major climate report released by the Trump administration revealed that global average sea level has risen by about 7-8 inches since 1900, with nearly half of that rise coming in the last 25 years.
Sea level changes, between 1992 and 2017. Senior scientist Dr Erik Ivins told BBC.
Sydney, on the other hand is expected to face the effects of ice loss in the Amundsen Sea Sector, a region in Antarctica farthest away from it, while the glaciers closest to the Australian city are less likely to affect it.
New York, for example, should mostly worry about three major glaciers in Greenland's northeast and northwest: the Petermann, Zachariae, and Jakobshavn glaciers.
For example, tool shows that changes to ice sheet in the northwest corner of Greenland will have a direct impact on sea levels for London over the course of 100 year, while NY will be most impacted by ice melting on the northern half of Greenland.
For example, when a glacier melts and loses ice mass, its gravitational attraction is reduced.
While melting land ice anywhere should concern coastal residents as the planet warms, this tool can help focus those concerns and make specific city projections more accurate.
The researchers verified their calculations using reading of ocean-bottom pressure from stations in the tropics.
