Dataset Details

Coupled Northwest Atlantic Prediction System (CNAPS)

CNAPS is a three-dimensional marine environment nowcast and forecast model. This fully coupled ocean circulation, wave, and atmosphere modeling system predicts conditions over a wide area of the coastal northwest Atlantic Ocean on a daily basis. The model domain covers from the eastern edge of Nova Scotia to the north coast of Venezuela, including the Gulf of Maine, Middle Atlantic Bight, South Atlantic Bight, Gulf of Mexico, Caribbean Sea, and western Sargasso Sea.
