Their usefulness is perhaps best captured by the surprise of some people to whom I have introduced NCO when they learned that it is a separate entity from the NETCDF library. The developers of NCO have always replied promptly to my help requests and have on occasion even added new functionality that I had requested. In my opinion, the advantages of NCO compared to mathematically more comprehensive packages reading NETCDF files are that it is fast, very concise, free of charge, runs on almost any platform, and can be easily integrated into shell or other kinds of scripts. And with the evolution of the ncap utility, the capabilities of NCO are becoming sufficient for tasks of greater numerical complexity. ------------------------------------------------------------ Dr. Maxwell Kelley Laboratoire des Sciences du Climat et de l'Environnement L'Orme des Merisiers CEA Saclay 91191 Gif sur Yvette cedex mkelley@lsce.saclay.cea.fr France +33 1 69 08 27 02 ------------------------------------------------------------ ************************************************************************ ************************************************************************ Subject: NSF SEI(GEO) NCO/SDO Proposal Endorsement From: <hjyang@pku.edu.cn> Date: Fri, 11 Jun 2004 15:49:46 +0800 To: zender@uci.edu The best netCDF processing software I have ever used.

Our group: http://paoc.mit.edu/cmi/ http://mitgcm.org/ and many of our collaborators are steadily moving toward the use of both hierarchical data formats (such as NetCDF and HDF) and multi-terabyte data sets. Under these circumstances, tools such as NCO become increasingly useful and important for our work. I am impressed with the capabilities offered by current NCO releases and would very much like to see it extended (per the above proposal) to take fuller advantage of parallel systems. I believe that such a free, open, and extensible set of parallel analysis tools would be an important resource for the GFD community. While nearly all ocean and atmospheric models have evolved to take advantage of parallel execution, it seems that many of the data analysis tools have lagged. Thus, for many researchers, it is the pre- and post-processing steps that consume the most time and can be the greatest barrier to experimental progress. Thus, I look forward to parallel versions of the NCO tools that will take better advantage of both our SMP (threaded) and cluster (MPI-based) computing resources.
