NCL Tools DocumentationFor an overview of the metafile tools listed below, see the "viewing and editing your metafiles" document.
- WRAPIT - wraps Fortran 77 or 90 code
so you can call it directly from NCL.
- ncl_filedump - generates an ASCII
representation of a supported file (netCDF, HDF, GRIB1, GRIB2,
shapefile) on the standard output.
- ncl_grib2nc - deprecated, use ncl_convert2nc instead.
- ncl_convert2nc - translates
GRIB1, GRIB2, shapefile, HDF, and HDF-EOS files that NCL can read to
- ng4ex - a script for generating hundreds
of available C, Fortran, and NCL object-oriented examples.
- nhlcc, nhlf77, nhlf90 -
scripts for helping to compile Fortran or C programs that depend on
the object-oriented HLU library.
- ctrans - translates an NCAR Computer
Graphics Metafile (NCGM) and interprets its instructions on the device
defined by the GRAPHCAP environment variable.
- ictrans - an interactive version
of the ctrans translator.
- idt (X window interactive image display
tool) - provides a graphical user interface to the NCAR View
interactive metafile translator ictrans.
- med - a metafile editor.
- psplit - splits PostScript files into
- scrip_check_input - checks on the integrity of
input grid files.
- NetCDF Operators (NCO) -
A suite of programs known as operators that can perform a variety of
operations on netCDF and HDF (Scientific Data Set) files.
- Free software which is frequently used to convert from one
format to another. We use it ourselves to convert PS files created by
NCL to PNG files that we can import into PowerPower and other aplications.
It may be used independently or implemented from
within NCL via the
Here's what we use to convert PS files to PNG:
convert -geometry 1000x1000 -density 300 -trim file.ps file.png
- mpeg2encode (part of the
"mpeg2vidcodec" package) - You can use this in conjunction with
"convert" from ImageMagick to generated MPEGs from a multi-frame PS
- A tool that allows you to create bitmap images from encapsulated
PostScript files. It uses Ghostscript to handle the conversion.
Supported output formats are PNG, JPG and GIF.
