24 July 2008, eaton Created using an updated version of CAM's interpic code: % set dir=/fis/cgd/cseg/csm/inputdata/atm/cam % ~eaton/interpic_new/interpic -v -t $dir/coords/fv_0.9x1.25.nc \ $dir/dst/dst_1x1.25_c060901.nc dst_0.9x1.25_c080724.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= 288 ny= 192 nz= 1 input min, avg, max = 0.000000000000000000E+00 0.186531580620818323E-01 5.70699999999999985 doing horizontal interpolation output min, avg, max= 0.000000000000000000E+00 0.186561151593856757E-01 4.57948991928175264 Did visual comparison of original and interpolated file using ncview. Looks OK, but highs in original have been significantly smoothed by the interpolation.
