This graphic, released on Dec. 10, 2020, shows the basic radar measurements, called waveforms, collected by the instrument that monitors sea level on the Sentinel-6 Michael Freilich satellite, which launched Nov. 21, 2020. The instrument, called an altimeter, works by bouncing a radar signal off the ocean surface and measuring how long it takes to go out and return. The higher-resolution waveforms focus on a smaller area of the ocean than the lower-resolution waveforms, allowing researchers to resolve smaller ocean features such as currents closer to the coast. The waveform provides information not only on sea level, but also on wave height and wind speed. https://photojournal.jpl.nasa.gov/catalog/PIA24136

This map shows sea level measured by the Sentinel-6 Michael Freilich satellite from June 5 to15. Red areas are regions where sea level is higher than normal, and blue areas indicate areas where it's lower than normal. The measurements are part of a set of data streams that become available to the public hours to a couple of days after the satellite collects them. The difference in when the products become available balances accuracy with delivery timeliness for tasks like forecasting the weather or helping to monitor the formation of hurricanes. The satellite, named after former NASA Earth Science Division Director Michael Freilich, collects its measurements for about 90% of the world's oceans. The spacecraft is one of two satellites that compose the Copernicus Sentinel-6/Jason-CS (Continuity of Service) mission. The second satellite, Sentinel-6B, is slated for launch in 2025. Together, they are the latest in a series of spacecraft starting with TOPEX/Poseidon in 1992 and continuing with the Jason series of satellites that have been gathering precise ocean height measurements for nearly 30 years. Shortly after launch in Nov. 2020, Sentinel-6 Michael Freilich moved into position, trailing the current reference sea level satellite Jason-3 by 30 seconds. Scientists and engineers then spent time cross-calibrating the data collected by both satellites to ensure the continuity of measurements between the two. Once assured of the data quality, Sentinel-6 Michael Freilich will then become the primary sea level satellite. https://photojournal.jpl.nasa.gov/catalog/PIA24533

Sea level data from the U.S.-European satellite Sentinel-6 Michael Freilich shows early signs of a developing El Niño along the equatorial Pacific Ocean. The measurements show Kelvin waves, low waves that can be tens of miles (hundreds of kilometers) wide, moving from west to east at the equator towards the west coast of Ecuador. When they form at the equator, Kelvin waves can move warm water – associated with higher sea levels – from the western Pacific to the eastern Pacific. El Niño is a periodic climate phenomenon that can affect weather patterns around the world. The condition can bring cooler, wetter conditions to the U.S. Southwest and drought to countries in the western Pacific such as Indonesia and Australia. El Niño is characterized by higher sea levels and warmer-than-average ocean temperatures along the western coasts of North and South America. Water expands as it warms, so sea levels tend to be higher in places with warmer water. The climate phenomenon is also associated with a weakening of the trade winds. The Sentinel-6 Michael Freilich satellite data shown here covers a seven-week period between the beginning of March and the end of April 2023. By April 24, Figure A, Kelvin waves had piled up warmer water and higher sea levels (shown in red and white) off the coasts of Peru, Ecuador, and Columbia. A series of Kelvin waves starting in spring is a well-known precursor to an El Niño. The waves seen during March and April 2023 are similar to the ones that preceded the 1997-1998 El Niño, one of the most powerful in recorded history. Satellites like Sentinel-6 Michael Freilich can detect Kelvin waves with an instrument called an altimeter that uses radar signals to measure the height of the ocean's surface. Warmer areas show up as higher sea levels. The satellite, named after former NASA Earth Science Division Director Michael Freilich, is one of two that compose the Copernicus Sentinel-6/Jason-CS (Continuity of Service) mission.
