17 December 2008, eaton Created using an updated version of CAM's interpic code: On calgary: % cd /scratch/cluster/eaton/interpic % set dir=/fs/cgd/csm/inputdata/atm/cam % interpic -v -t $dir/coords/fv_0.47x0.63.nc \ $dir/dst/dst_1x1.25_c060901.nc dst_0.47x0.63_c081217.nc From the verbose output of interpic: Interpolating mbl_bsn_fct_geo input: shape= xy nx= 288 ny= 181 nz= 1 output: shape= xy nx= 576 ny= 384 nz= 1 input min, avg, max = 0.000000000000000E+00 1.865315806208183E-02 5.707000000000000 doing horizontal interpolation output min, avg, max= 0.000000000000000E+00 1.864594562034208E-02 5.343169762004471 Did visual comparison of original and interpolated file using ncview. Looks OK.
