Name        : ncl
Product     : Fedora 18
Version     : 6.1.0
Release     : 1.fc18
URL         : http://www.ncl.ucar.edu
Summary     : NCAR Command Language and NCAR Graphics
Description :
The NCAR Command Language (NCL) is a free interpreted language designed
specifically for scientific data processing and visualization. NCL has robust
file input and output. It can read and write netCDF-3, netCDF-4 classic (as
of version 4.3.1), HDF4, binary, and ASCII data, and read HDF-EOS2, GRIB1 and
GRIB2 (as of version 4.3.0). The graphics are world class and highly
customizable.

As of version 5.0.0, NCL and NCAR Graphics are released as one package.

The software comes with a couple of useful command line tools:

  * ncl_filedump - prints the contents of supported files (netCDF, HDF,
    GRIB1, GRIB2, HDF-EOS2, and CCM History Tape)
  * ncl_convert2nc - converts one or more GRIB1, GRIB2, HDF and/or HDF-EOS
    files to netCDF formatted files.

Update Information:

Version 6.1.0 represents a major overhaul of the graphics display model, which allows for:

- The use of transparency via RGBA (alpha) values
- Using named colors ("PaleGreen") without having to add them to your color map
- The use of more than 256 colors per image

We've also changed some graphical defaults, which we think will be a big improvement:

- Default color table has been changed to one with 256 colors
- Default font is now "helvetica"
- Default function code is now "~"
- The color map will automatically be spanned for colored vectors, contours, and streamlines
- The labelbar labels will automatically be strided if they overlap.

Some other new features include:

- New regridding functions via ESMF (Earth System Modeling Framework) software
- Several new functions, color tables, and resources
- Improvements to GRIB1/GRIB2 and NetCDF4 reader
- Bug fixes
