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