Sentinel-6 Satellites Track Ocean Conditions During El Niño to Aid Hurricane Forecasts

NASA says Sentinel-6B and Sentinel-6 Michael Freilich are measuring ocean height, waves, marine winds and atmospheric properties during El Niño. The observations are intended to improve understanding of storm-fuelling ocean conditions and support hurricane-intensity forecasting, although a quantified forecasting improvement has not yet been reported.
