Converting HiRes to LowRes

[M.Mahakur]

Respected GrADS Users:

How can I convert a high resolution variable to coarser resolution (e.g.
from 0.1x0.1 to 0.5x0.5 or 0.5x0.3 degree) using the 'aave'. Any script?
to loop aave centered on the new grid. I need to do simple averaging and
not any kind of interpolation (like regrid2 does).

Thanks in advance.

With Regards,

M. Mahakur

P.S. Sending agaian as I did not get any response.
