[cam-users] How can I interpolate SST data?

[Xuguang Sun]

Hi, everyone,
  I have sst dataset which has no values on land, and
I want to interpolate it for ccm input sst data with
interpsst which CCM supplies. But after I perform the
command "interpsst -x 128 -y 64 xxx1.nc xxx2.nc", I
found the values in xxx2.nc were constant -1.75. The
xxx1.nc is ok when to graph it. So what's the matter
about my interpolation? Can anybody give me some
suggestions?
 Thank you.
