SampleWindTables.mat

I have 70 tables, all with the same column headings saved in a .mat file. I would like to be able to loop through the tables to create new arrays of different variables contained in the tables. For instance, one of the column headings is latitude. I would like to be able to loop through all 70 tables, grab the latitude value from each one, and make a new 70 x 1 array with these values. Can someone help me with the best way to accomplish this? I'm attaching the a portion of the .mat file that contains the tables. Thanks!

Some of the column variables contain thousands of values, so I'm not sure that would work.

I'm wondering if perhaps it would be easier so work with 70 structs? or alternatively 24 tables?

edit: yes I understand, I deleted my first comment after realizing I was looking at the wrong table :) It would still work, you'd have to learn how to effeciently group data.
