Since 1999, a cooperation between University of Hamburg and University of
Hawaii has been set up on common research concerning applications of HF radar.
As in August 2002, the first two WERA HF radars have been deployed at the
shore of Oahu to measure the ocean circulation between Oahu and Kauai in the
frame of the Home project.
More information can be found at the Uni Hawaii
HF radar pages.
This is an example of surface currents measured by the Hawaii WERA:
Ko Olina (radial)
current map (GDOP<3.5).
Note that too narrow or wide angles between the radial components increase the
error of the current vectors. The 'error increase factor' GDOP (Geometrical
Dillution Of Precision) has been limited to 3.5, which reduces the area
covered. The figures shown are based on 10 minutes integration time and
no filtering applied. The HF radar working frequency is ~16.0 MHz.
