<DIV>you should use an exist grid file to output interpolated matrix.</DIV>
<DIV>following is an simple guide...</DIV>
<DIV>file.1 file.2 are your files</DIV>
<DIV>file.3 is an exist grid file with resolution of 0.333*0.333, which you can
create yourself.</DIV>

<DIV>
<DIV>Hi. I'm trying to regrid two files to a common grid. The two files have </DIV>
<DIV>different resolutions and projections. Here is the detail for the files:</DIV>
<DIV> </DIV>
<DIV>file 1 (model)</DIV>
<DIV> Type = Gridded</DIV>
<DIV> Xsize = 428 Ysize = 322 Zsize = 1 Tsize = 1198 Esize = 1</DIV>
<DIV> Number of Variables = 1</DIV>
<DIV> px1 1 t,z,y,x px1</DIV>
<DIV>X is varying Lon = -140.885 to -94.7226 X = 1 to 428</DIV>
<DIV>Y is varying Lat = 22.4263 to 57.129 Y = 1 to 322</DIV>
<DIV>Z is fixed Lev = 1 Z = 1</DIV>
<DIV>T is fixed Time = 00Z01JAN1961 T = 1</DIV>
<DIV>E is fixed Ens = 1 E = 1</DIV>
<DIV> </DIV>
<DIV>file 2 (NARR)</DIV>
<DIV> </DIV>
<DIV> Type = Gridded</DIV>
<DIV> Xsize = 107 Ysize = 80 Zsize = 1 Tsize = 384 Esize = 1</DIV>
<DIV> Number of Variables = 1</DIV>
<DIV> pmax1 1 t,z,y,x pmax1</DIV>
<DIV>X is varying Lon = -140.885 to -94.7226 X = -1081.74 to -943.241</DIV>
<DIV>Y is varying Lat = 22.4263 to 57.129 Y = -15.7149 to 88.4036</DIV>
<DIV>Z is fixed Lev = 1 Z = 2</DIV>
<DIV>T is fixed Time = 00Z01JAN1961 T = -215</DIV>
<DIV>E is fixed Ens = 1 E = 1</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>I would like to regrid to 25 km or 1/3 degree so I can calculate </DIV>
<DIV>anomalies between the two.</DIV>
<DIV> </DIV>
<DIV>thanks</DIV>
<DIV> </DIV>
<DIV>Robert</DIV>
