NetCDF-Java library version 4.5.5

The NetCDF-Java/Common Data Model (CDM) library version 4.5.5 was released on March 6, 2015. The development team recommends this upgrade for anyone using the CDM. (THREDDS Data Server (TDS) version 4.5.5 is also available as a beta-test release.) The latest update can be downloaded from:

About this version

Version 4.5.5 includes serveral bug fixes and improvements, including:

  • fixing a memory leak when processing netcdf4/hdf5 files
  • fixing a bug with nested aggregations not working when caching was on, eg in TDS
  • fixing a bug handling client-side certificates
  • better handling of scalar runtime coordinate for GRIB collections
  • an upgrade to ncWMS
  • fixing NIDS start/end dates
Note on handling of GRIB files

Version 4.3 included a complete rewrite of GRIB1 and GRIB2 file handling, intended to correct problems that exist in version 4.2's handing of tables (especially in non-NCEP files) and time interval coordinates. If you are upgrading from version 4.2, please read the Notes to GRIB users.

The NetCDF-Java development team at the Unidata Program Center strongly encourages operators of sites that take advantage of the CDM libraries to install the latest version and forward any potential issues to the development team via Unidata's support system (support-netcdf-java@unidata.ucar.edu) or the user community mailing list (netcdf-java@unidata.ucar.edu). Real-world use of new features by the user community is integral to the process of creating and refining these libraries.

I just only want to extract some data from GRIB-Files NC-Files, and write them in an file in ASCII. There is no command in your historical and unuseful procedures. The only thing I can do is writing to standard output which is complete rubbish, as it can't be used by other programs.

And there is no readable desription of the structure of the data and how variables can be read by other programs.

Do you want to be a secret community?

Currently, I am using the netcdf 4.6.3 java library to read data from grib1 and grib2 files. I was able to open the file, which gives me at a certain point a "VariableDS" object. This object 'knows' its data came from a grib1 file. Now I am trying to get the decimalScalefactor of the original gribdata through the getBinaryDataInfo of the grib1Record class, but for this I need a grib1Record. How can I search this record in my dataset or is there another way to get to the decimal- and binaryScalefactor ? Thx for your answer!

Hi Robert,

Would you mind sending your question to our netCDF-Java users list? netcdf-java AT unidata.ucar.edu.

Thanks!
