Here I think a good way to treat the data in three datasets as one variable will be to call a function which concatenates them.
The way I wrote that, this will put AD03_temp[d=3] at y=12, AD03_temp[d=2] at y=15, and so on. If this is not the correct order, change the order of concatenation. Now, if you use the variable temp_grd_xy, Ferret will read the data from each file as needed.
