Hi Suvarchal,
We have a few area average formulas available, such as
rects(field, D=2) for the rectangular aperature smoothing, and you can
check out the Jython libraries under Grid Diagnostics. There is also a
formula named getNthTimeGrid(field, Nth) for your second request under the
Grid Routines.
