title: Change resolution of half-degree netCDF to quarter degree netCDF using nco tools
body: <p>I can change the resolution of a netCDF file to a coarser one by doing something like this:</p>
  
  <pre><code>ncks --dmn lon,0,1384,5 --dmn lat,0,583,4 original.nc reduced.nc
  </code></pre>
  
  <p>How do I go the other way? I.e. change resolution of coarser scale netCDF to finer scale?</p>
