Example spatio-temporal climate data

[carocamargo]

This pull request is to load a SOM example on climate data notebook, which is usually 2D (time, lat, lon).

I've been looking a lot into SOM examples, and it's hard to find examples on climate data...so I hope this notebook can help future users (and also me, if you find something wrong on the use).

For the example, I've used the tutorial dataset from Xarray.

hi @carocamargo

this is a wonderful contribution!

Can I just ask to leave a comment under each chart? Just to give a basic understand to less experienced readers.

Hi @JustGlowing, I've added some comments under the plots... please tell me if they require more details.
I also have a notebook where I'm trying to optimize the hyperparameters using hyperopt. I think it automatically went in this pull request as well (although I'm not 100% of the output of this method yet).

SOM-spatiotemporal_climate_example.ipynb
Updated example with better plots description + added an example of 2D SOm on the spatio-temporal data (using time-mean field)

SOM-spatiotempeoral_climate_example-Part_II.ipynb
Continuation of the previous example, now trying to optimize the parameters used in the SOM.

I think I've pushed the changes, let me know if they didn't go through.

hi there,

Sorry it took a while to review the material. I'm happy to merge the first notebook, but the second one seems to advanced respect to the examples already in the library.

I do plan in including a notebook regarding parameter optimization in the future, but I'd like it to be a more straightforward example.
