Been there, done that. ;-)

Here's a Jython method that will take the average of a sequence of
images:

def average(grid):
   from ucar.unidata.data.grid import GridUtil
   if (GridUtil.isTimeSequence(grid)):
       len = grid.length
       avg = grid[0]
       for i in range(len-1):
          avg = avg + grid[i+1]
       return avg/len
   return grid

you could use a similar method for calculating other statistical
parameters.

Eventually, we'll move this into the core.
