Standard CODAR Real-Time Archive Data

CODAR is used to measure the surface currents of the coastal ocean. A transmitter sends out a radio frequency that bounces off the ocean surface and back to areceiver antenna. Using this information and the principles of the Doppler shift, CODAR is able to calculate the speed and direction of the surface current. These calculations are made at about every half mile across the surface and extend as far as about twenty miles offshore. CODAR Archived Data for Standard and Long-range CODAR System is available online for 1998, 1999, 2000, 2001, 2002 and 2003.
