interpolate 3 dimensional arrays (in time and space)

Hi all,
I have 3D matrix 180x90x120 which is equal to lonxlatxtime. In space, the data has 1 degree resolution (e.g. longitude ranges from 1 to 180), while the time interval is 3 hours (e.g. 3h, 6h, 9h.....).
Now I want to interpolate data to get a finer resolution of 0.5 degree and with 1-hour interval, so the new matrix would be 360x180x360.
Could you please help?
Thanks

No, do not use griddata for this. KL's suggestion of griddedInterpolant was appropriate. See also my second answer.

Those will not be the new dimensions. If you sample from 1 to 180 at intervals of 0.5, you will obtain 359 points, not 360. Similarly for the other dimensions.
