![]() NcBrowse allows the user to export parts (or all) of a file in the sameįormat as the ncdump command (described elsewhere in this document). The interface is largely self explanatoryĪnd provides a wonderful method for browsing generic netCDF files. The WOCE Global Data V3 set are COARDS compliantĪnd therefore should allow the automatic display of plot elements such as NcBrowse has been extended over the earlier versions. (Max OSX) which have the Java Virtual Machine installed. It can run on UNIX (and linux), Windows and Macintosh's This command allows the contents of variables, global attributes This command is a Java application and can be obtained at the EPIC Standard for all the different data types within the WOCE Global DataĪnd also are common to other data sets that are used by the oceanographicĪnd meteorology communities. This means that the variables names associated withĭata, the attributes of the data and the time convention follow a common The WOCE Global Data V3 are now in a Cooperative Ocean/Atmosphere ResearchĬompliant format. Matlab, IDL, Fortran, C, ncdump, and Ferret. Here we focus on reading netCDF files with ncBrowse, Such as Ferret, GMT and GrADs and commercial products such as MATLAB, NCAR That uses netCDF for input are also listed at these sites and includes products This siteĪlso contains excellent description of the Fortran (also Fortran 90), JavaĪnd Perl interfaces for netCDF files. They can be obtained from UnidataĪnd are available for Unix, Windows and Macintosh based systems. It is assumed that netCDF libraries have already been installed on your Time for analysing data and addressing the synthesis of the WOCE Global User, high efficiency in reading netCDF files and multiple data can be readilyĪchieved as shown in the examples below. In many of these packages the axes can be labelledĪlthough there is an initial learning curve for the inexperienced netCDF Ferret, IDL, MATLAB) can directly read the netCDF files Whether it be Fortran, C/C++, Java or Perl. Secondly, it means that programs describedīelow can read a netCDF file and generate the code needed to read the reducing the incidence of errors)Īvailable with the data themselves. This self-describing aspect of netCDF file format means that the information Their structure, the variables' names and essential metadata such as the This means that software packages can directly read the data and determine Many advantages, the most important of which is that it is self-describing. Why use netCDF for the WOCE Global Data VersionĪll of the WOCE Global Data is now in netCDF format. Preserves much of the original information in the data set reducing theĬhance of errors occurring during analysis. Such as the source, creation date, investigator, position, etc). (such as units) and name are defined in the data set (along with other information This reduces the hurdles involved in reading all the different data setsĪnd allows the analyst to concentrate on the interpretation of the observationsĪs the netCDF files are self-describing, the attributes of each variable On the WOCE Global Data Version 3.0 DVD, the skills required to read oneĭata set are the same as those needed to read all the others data sets. To traditional languages such as Fortran, C/C++ and Java.īecause netCDF format is now used for all of the different data products These toolsĪllow the netCDF files to be read quickly and easily and to be manipulatedīy many common analysis packages such as ncBrowse and Ferret in addition Of netCDF files found in the WOCE Global Data Version 3.0 DVD. The following describes some simple tools that are available for the reading Appendix 2: Example matlab script for current meter.Appendix 1: Readnet.for created from cdf2fortran.Other methods for examining netCDF files.Why use netCDF for the WOCE Global Data Version 3.0.For more information please refer to the MATLAB documentation on the Mathworks web site. It should, however, be noted that much of the information it contains is now redundant as Mathworks has introduced a native netcdf toolbox in MATLAB.
