doh! I was looking @

rather than the ESMF examples @

Thanks! The latter example esp looks helpful. Two more questions:

1. The Regrid3D example uses data with filename=

so_Omon_GISS-E2-R_historicalNat_r5i1p1_185001-187512_2timesteps.nc

   Is that available somewhere? (It did not google.) Might be useful for
   folks "playing along at home."

2. I gotta rewrap my head around the python/numpy way of doing things.
   Can you recommend any user-level ESMF tutorials oriented toward this
   relatively low-level task (regridding)? Most of what I see (e.g. @

http://www.earthsystemmodeling.org/users/getting_started.shtml

   ) seems more oriented toward designing/developing for a full-blown
   ESMF-based model, i.e., substantially conceptually more high-level.

http://www.earthsystemmodeling.org/esmf_releases/non_public/last/regridding_status.html

   is more like what I need, though it doesn't seem to point to
   code examples.

thanks again, Tom Roche <Tom_Roche@xxxxxxxxx>
