1. Singular Value Decomposition North Atlantic SST
What spatial patterns exist in Labrador SST anomalies?
What about North Atlantic SST anomalies?
How much variance of these regions do these EOFs explain?

2. Data Description Labrador Sea SST North Atlantic SST
Combination of SEAFLUX SST and Reynolds SST
Originally 3 hourly, averaged into monthly
1988 – 2000
144 time steps
50N – 75N, 70W – 40W
Every 0.25 degrees
North Atlantic SST
Reconstructed global sea surface temperature based on COADS data
Monthly
Dec 1870 through Feb 2004
402 time steps
0 – 80N, 100W – 0
Every 2 degrees

3. Method Remove the means in data set
Construct a matrix where each column is a point in the domain and each row in the column is a time step
Remove the columns where there is missing data (NaNs)
Perform the SVD analysis
To remap the EOFs, replace the missing data in the new grids
