Jason-3, a joint mission between NASA, the European Space Agency (ESA), and the French space agency CNES, uses radar altimetry to measure sea surface height with great precision. This information can be used to monitor changes in ocean currents, sea levels, and wave patterns, all of which are affected by El Niño.
By tracking sea surface height, Jason-3 provides valuable data for scientists and forecasters who are monitoring the evolution and potential impacts of El Niño. This information helps to improve predictions of how the phenomenon might affect different regions and allows decision-makers to take appropriate actions to mitigate potential negative impacts.
In addition to its role in monitoring El Niño, Jason-3 also contributes to a wider range of oceanographic research and applications, including climate studies, sea level rise, ocean circulation, and marine life habitats. The satellite's data helps to advance our understanding of the ocean's role in Earth's climate system, and supports efforts to manage and protect marine resources.
