[NARCCAP-discuss] netcdf to raster files in ArcGIS

[Philip Morefield]

Risa-

When I started working with NARCCAP way back when, I ran into the same
problem you did. ArcGIS is too slow to convert thousands and thousands
of time steps.

I built a custom ArcGIS tool to process NARCCAP files. It's basically an
aggregation tool, so it generates monthly/seasonal/annual averages in a
matter of minutes, or even seconds. It's somewhat crude, but it does
work. In a few months an improved tool will be out that is more flexible
and has a better GUI.

I can provide you (or other interested parties) with the uglier version.
There are some caveats:
      The tool doesn't work with any of the ECP2 or HRM3/HADCM3 runs.
      ArcGIS problems there, which I believe have been discussed on this
      listserv.
      ArcGIS can't easily replicate the rectangular grid cells of the
      GFDL time slice run (I submitted a bug report about a year ago).
      The output is internally resampled to a square cells.
      Windows operating systems only. Installation rights will be
      needed.

If anyone is interested, let me know via email.

Dear Gui,

Yes, I did. But I didn't know there is the option to convert to kmz or
csv.
Anyways, I need to convert thousands of files so I need an automatic
program to do this.
