Which space mission is useful to get water level in earth surface

When SWOT reaches its destination 553 miles above Earth's surface, a new era in the study of The This joint mission of NASA and France's National Center for Space Studies is supported by a unique alliance of Earth scientists eager to answer key questions about flooding, climate patterns and our future water supply. The satellite will be able to see through storm clouds and accurately measure the height of flood waters when terrestrial gauges are submerged. If a country refuses to share information about its water usage along a river, the spacecraft will be able to provide it instead. SWOT is designed to observe the planet with unprecedented precision and frequency, returning reams of data to help scientists and policy makers plan for floods, droughts and Scientists say the $1.2 billion mission has the potential to change our understanding of Earth's water as significantly as the microscope changed our view of the human body. "The possibilities are so endless that I'm almost not sure where to start," said Tamlin Pavelsky, a global hydrologist at the University of North Carolina at Chapel Hill and the mission's hydrology science lead. "It's like whacking a piñata with a baseball bat and having all this candy pour out, and you just don't even know what to grab first." Previous satellites have monitored either oceans or fresh water. SWOT will be the first to observe both. The mission is a joint effort in oceanography and hydrology—two related scientific disciplines that are of...

This visualization shows water features on New York’s Long Island—shown as bright pink splotches. Purple, yellow, green, and dark blue shades represent different land elevations, while the surrounding ocean is a lighter blue. The data was collected on Jan. 21, 2023, by SWOT’s KaRIn instrument. Credit: NASA/JPL-Caltech The international Surface Water and Ocean Topography (SWOT) mission—led by NASA and the French space agency Centre National d'Études Spatiales (CNES)—has sent back some of its first glimpses of water on the planet's surface, showing ocean currents like the Gulf Stream in unprecedented detail. SWOT is also capturing views of freshwater features such as lakes, rivers, and other water bodies down to about 300 feet (100 meters) wide. The satellite will measure the elevation of nearly all the water on Earth's surface and provide one of the most comprehensive surveys yet of our planet's surface water. SWOT's measurements of freshwater bodies and the ocean will provide insights into how the ocean influences climate change and the "SWOT's advanced imagery will empower researchers and advance the way we manage fresh water and the effects of sea level rise across the globe," said NASA Administrator Bill Nelson. "Water is one of our planet's most important resources—and it's proven to be vulnerable to the impacts of A whole new view As seen in these early images, on Jan. 21, 2023, SWOT measured sea level in a part of the Gulf Stream off the coast of North Carolina and V...
