The NetCDF tools are a few tools to operate on NetCDF and, by utilizing the compatibility API, HDF4 files, and intended to be used from the Shell scripts.
The NetCDF tools package is currently comprised of a couple of simplistic Shell wrappers over the respective NetCDF functions (ncattget and ncattput), and a more sophisticated ncget tool.
The ncget tool
The ncget tool implements a like to (for NetCDF), or complements the hdp dumpsds (for HDF4) functionalilty, and allows a selected part of a NetCDF variable or an HDF4 scientific data set (SDS) to be extracted in either an ASCII or binary (machine float, machine double, or as-returned formats) form, optionally applying the transformation specified by the scale_factor and add_offset attributes.
This tool allows to feed NetCDF variables' (or HDF4 SDS') data to tools, designed to operate on either ASCII (text) or raw (binary) data.
The tool complements the standard HDF4 hdp tool in the following ways:
* the scale_factor and add_offset attributes are applied; these could be overriden by the respective command line options;
* the data could be extracted in the binary machine single- or double-precision floating point number form, as well as the raw form (the same form as returned by the respective library calls) and the ASCII form;
* GNU long options are supported, allowing for better self-describing Shell code.
The authors don't know a software providing a similar functionality for the NetCDF files.
