Extracting Modulated Annual Cycle in Climate and Ocean Time Series Using an Enhanced Harmonic Analysis

Table 2

The IP number making the smallest RMSE the smallest in the annual cycle extraction of simultaneous changes in amplitude and phase. NPR is the noise-power ratio.

NPR (%)	EX 8	EX 9	EX 10	EX 11	EX 12	EX 13	EX 14
1	6	6	7	8	9	9	14
2	4	4	6	10	10	9	17
4	4	4	4	8	9	8	14
