Hi @dabail10 , thanks for making these additions!

I also have a few very minor change requests:

1. Could you please title your notebooks something descriptive? Our recommended format is <region>_<variable>_<metric>_<comparisons>.ipynb; for instance, this might look like Global_PSL_NMSE_compare_obs_lens.ipynb or Greenland_SMB_visual_compare_obs.ipynb.
2. It looks like there is some commented out code in both of the notebooks-- if this is not going to be used, can you please remove it? Or, if the commented out code is going to be used in some circumstances, maybe it could be in a in 'if' statement?

I have addressed the first part. I need some of the commented out code as I want to use this eventually for reading the LENS data.

I have got this to work (at least read data) with the examples/key_metrics/config.yml file. I am still working on the computing of an annual average. The new way of reading in the datasets messed up my resample/groupby. More to come.
