The NASA Jason-3 Program aims to monitor and measure ocean surface topography in order to improve our understanding of ocean currents, climate, and weather patterns. The program is a collaboration between NASA, the National Oceanic and Atmospheric Administration (NOAA), the French space agency CNES, and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). The Jason-3 satellite launched in 2016 and uses radar altimetry to measure the height of the ocean surface with unprecedented accuracy. The data collected by the satellite is used to create global sea surface height maps, which are crucial in predicting weather patterns and in monitoring the effects of climate change on the world’s oceans.
