function to collocate insitu and satellite data

[sevfour]

• take 1d xarray insitu data from Kyla and collocate each measurement to satellite
• include SSS and SST

I finished one test code to collocate SMAP SSS data with one SIZR file for 2016. @kdrushka you can try to run it. At some point in the code, where i do the interpolation, i use a loop and that's not ideal at all but i couldn't find a way to make the 3D interpolation work with xarray interp() (but i'm sure it's possible).

Sweet! 🙌

I think the 3d interp wasn't working because we had non-unique times for SMAP files so they were loading more than once.

I added two things, one to only load SMAP files once, and two to do a 3-d interp along a new dimension. Let me know if this is what you had in mind/make sense...

That's great! Thanks :-)

I have added the collocation to OISST L4 data in the test notebook.
I made a .py file to run the collocation with SIZRS file for a certain date/region of interest. It seems to work!
