<p class="MsoNormal">Hello,<o:p></o:p></p>

<p class="MsoNormal">I am having issues using gdalwarp to resample climate data to a finer resolution. Each climate raster has been clipped to the extent of Alaska, and contain >300 layers (1 for every month from 1979-2010). The current resolution of the rasters
is >1000 km and they need to be resample to around 33 meters, making the new files go from ~8 MB to 33 GB. I have been testing out gdalwarp on these files but so far I cannot get them to resample in a reasonable amount of time. I ran one for over 15 hours
on my universities campus cluster and it never passed the 0% complete mark. I need to be able to get each file done in less then 48 hours since that is the time frame limit on the cluster.
