Validation, Significant Wave Height, Wave PeriodAbstract
This work is a validation effort of reanalysis data from ERA-Interim project needed to estimate the ocean wave power. To this end, statistical analyzes were performed, comparing them with data obtained from indirect measurement by satellite altimetry Jason-2/OSTM. Two different methods estimated the wave period once the altimeter satellites do not measure this data. As a result, a strong correlation was found, since in seven of eight points analyzed bias is kept below 0.16, and Pearson coefficient close to or greater than 0.7. The other statistical parameters also showed good results, such as scatter index always less than 0.25, RMSE generally low and the ratio of standard deviations close to 1. With respect to the wave period, the results were not conclusive, but the qualitative analysis indicates a trend between the data series.
