Again, I'm really not trying to be a jerk. But it's very hard to answer your question without knowing the details of the data. As a general rule, no one will look at a segment of code that they can't immediately dissect in the time it takes to drink a gulp of coffee (and that's killing your other questions). Here I can see what you want. But, I don't know what the structure airport looks like. Give us the output of the following two commands:

help,airport

and

help,airport,/structure

Then we have a good idea how to help you...

I was expecting a 2D array for adatea. I can see how its putting the matching columns and rows into the 1D array but it makes it more complicated when I want to plot the temperature profile for that corresponding date. Is there another way to do this?

Your question doesn't make a lot of sense without knowing more about the data, parituclarly the structure: airport. In any event, look at array_indices, it's a way of
