The Sentinel 3B altimeter was launched in April of 2018 and completed full commissioning in late fall of 2018. The measured data began flowing into Oceanweather’s forecast systems as of January 2019.
Data from altimeter satellites such as the Jason and Sentinel series are used to adjust the model forcing for the wave simulations. Data are both objectively and forecaster controlled for quality assurances and allow the forecaster to quickly see where the wave analysis is both higher or lower than measured. These areas can then be manually corrected to produce more accurate analysis and thus forecasted wave train simulations.
