=****Empirical Orthogonal Functions (EOF) homework.** ** = ===****Background reading: Hsieh book chapter 2** ** ===

===****1. First, a question about the sense of EOF's:** ** ===
 * 1) How many values (numbers) are in your input data array? 240 x 144, in format longitude vs. time
 * 2) How many values (numbers) are needed to build each term on the left? 144 for EOFs, 240 for PCs
 * 3) If 5 EOFs capture most of the data's variance, how much smaller (in the above sense) is the EOFxPC representation compared to the full data set? 240 * 144 - (240 + 144) * 5

===****2. Read in your field1 (let's call it x again). Use the same data from HW3 data source here.** ** ===


 * Perform and display an EOF analysis of your first field.**
