This is an R Notebook to help visualize the results of your results. Pretty cool huh?

Some directions: Execute chunks by clicking the Run button within the chunk or by placing your cursor inside it and pressing Cmd+Shift+Enter.

Add a new chunk by clicking the Insert Chunk button on the toolbar or by pressing Cmd+Option+I.

When you save the notebook, an HTML file containing the code and output will be saved alongside it (click the Preview button or press Cmd+Shift+K to preview the HTML file).

The preview shows you a rendered HTML copy of the contents of the editor. Consequently, unlike Knit, Preview does not run any R code chunks. Instead, the output of the chunk when it was last run in the editor is displayed.

Visualize SST data for example year 2010 (La-Nina year)

Visualize SST data for example year 2015 (El-Nino year)

Question 1. Can you notice any major differences between the years in SST in the Pacific Ocean?

Answer: There is a very slight difference when looking at the images together up close. This is most noticeable on the very left of the figure in the pacific ocean where the dark red spot grows a slight amount.

You probably noticed that it’s a bit difficult to just look at SST between years and

#see differences. SO we are going to visualize the actual differences

Question 2. What do you notice? Is it easier to visualize the differences?

Answer: No, it looks about the same as the previous figure where it is difficult to tell with very minimal/slight changes.

##Let’s try making it a little easier. But how do we do that? Well we need to know the scale that the differences span

Question 4. Explain the trends in SST differences between an el nino and la nina year. In your answer point out specific oceanic regions. Are there widespread changes? Not just the Pacific Ocean?

Answer: This final graph makes is much clearer to see the difference. The largest difference can be seen in the pacific off the coast of California and along the equator. In the North Atlantic we see a -2 change meaning it was colder.
