Is there any way to automatically "crop" an array?

Say I've got a 2-D array (lat/lon) that has a blob of data in the middle
surrounded by missing values. Is there an NCL function that will
automatically crop or trim that array to the edges of the data, thereby
getting rid of the surrounding cells of missing data? Just curious since I
don't see anything in the function list that appears to do this.
