I would look at other tools for doing calculations on multi-dimensional 
NetCDF files. I've used NCO in the past for this,[1] which can average a 
time dimension in a 3D grid to produce a 2D grid (which can be converted 
to any other raster format using GDAL). You can do much more with NCO 
utilities. However, NCO is not user-friendly, since it is command-line 
work, requires a lot of documentation reading to understand the usage, 
and is available for almost all operating systems except MS Windows.
