2.0 Using ncBrowse
to read netCDF file
This command is a Java application
and can be obtained at ( http://www.epic.noaa.gov/java/ncBrowse/
). This command allows the contents of variables, global attributes to
be viewed graphically. It can run on UNIX (and linux), Windows and Macintosh's
(Max OSX) which have the Java Virtual Machine installed (see the above web site
or the Java web sites
http://java.sun.com/products/jdk/1.2 , http://java.sun.com/j2se/1.4/
NcBrowse has been extended
over the earlier versions. It now works with both
COARDS and EPIC
compliant netcdf files. The WOCE Global Data V3 set are COARDS compliant
and therefore should allow the automatic display of plot elements such as labels
and variable names and units. The interface is largely self explanatory
and provides wonderful method for browsing generic netCDF files.
2.1 Exporting netcdf files
ncBrowse allows the
user to export parts (or all) of a file in the same format as the ncdump command
(described elsewhere in this document). Thus, for many users who require
the analysis of relatively few data files , ncBrowse can provide the first quick
look at the WOCE, and should the data require further calculation allow export
of the data to a flat ascii file.
2.2 OPenDAP files
The WOCE Global Data V3
data are also to be delivered over the world wide web. ncBrowse also includes
the capability to browse the WOCE netcdf files over the web using the
(formerly know as DODS). This feature means that the WOCE Global Data
V3 data set doesnot need to be resident on your local hardware.
Installation of JAVA is
straightforward under Windows and Linux (Redhat 7.1) and ncBrowse installs very
easily on top of this.
This product is well worth
installing and using for the quick plotting and export of netCDF files
as part of the
WOCE Global Data V3.
