Better Data Means Better Forecasts Saildrone’s mission is to collect and share more data about the planet. The oceans cover more than 70% of Earth’s surface and drive weather, regulate temperature, and ultimately support life on Earth. Much of the weather we experience on land starts in the oceans, so we believe weather forecasting should start in the oceans, too. Our global fleet of saildrones continuously sails the world’s oceans collecting atmospheric and oceanographic data. These expeditions generate unmatched, proprietary high-resolution data sets that are used by scientists at the world’s leading science organizations to better understand air-sea interactions and improve long-range weather forecasting and prediction of extreme weather events.

BayCurrents is a mobile app for displaying maps of high resolution surface currents within the San Francisco Bay. The app is intended to support a wide range of maritime activities, from recreational fishing and sailing to the operation of professional transport vessels. The source for the surface current data is a numerical model operated by the National Oceanic & Atmospheric Administration (NOAA). The model benefits from oceanographic high-frequency radar (HFR) measurements from the Central & Northern California Ocean Observing System (CeNCOOS) HFR Network, along with other observations such as tides and wind. The resulting dataset contains current vector fields for hourly timestamps ranging from the recent past, to the present and up to 48 hours into the future. The complete vector dataset is downloaded by the app to allow autonomous offline operation. This app contains experimental data and is NOT for navigational purposes.
