Hi all,
CDO has many operator for regridding.
See https://code.zmaw.de/embedded/cdo/1.5.4/cdo.html#x1-4870002.12
But my tries with conservative remapping on curvilinear grids have not been
very concluding (impossible to specify that precalculated arecells have 
to be used).

Another point. NCL has annonced that next realease 6.1 will present new 
regridding capacities
based on the use of software from the Earth System Modeling Framework 
<http://www.earthsystemmodeling.org/> (ESMF).
Read http://www.ncl.ucar.edu/Applications/regrid.shtml

With pyferret, those ESMF regridding functions may be easier to include.

Regards
Patrick
