A Reanalysis of North Pacific Sea Surface Temperatures Using State-Space Techniques: The PDO In A New Light
North Pacific sea surface temperatures (SST), as used in estimating the PDO, are reanalyzed using state-space decomposition and subspace identification techniques. The reanalysis presents a very different picture of SST in this region. The first common trend reflects a global warming signal. The sec...
