This study analyzed long-range CODAR data collected at two stations (Suao and Hanban) in the northeast Taiwan. Two methods were applied, the software provided by CODAR and the radial velocity reversion least-square method, to calculate the true flow. The former method applied to data collected during 2011/03/ 03 to 2012/03/15, while the latter applied to data of 2011/09/01 to 2011/10/31. Results of data analyses showed that (1) Current speed increased in the summer with maximum of 1.5m/s and reduced to a minimum of 0.5 m/s in the winter. (2) Reasonably good data can be obtained using both methods for data collected in the angles between 15 ° and 165 °. (3) Current velocity data computed by the above two methods has a cross correlation coefficient 0.56. The major differences occurred at the edges of CODAR coverage area. (4) The weekly averaged geostrophic currents suggest that the radial velocity reversion least-square method providing a better result than those of CODAR software. (5) EOF analysis of long term CODAR records showed that the first mode accounted for 40% of total variance. The northeast monsoon is important to the surface flows in this region.
