If you are not using GRIB files, you can ignore this.We are experimenting with different ways to create stable GRIB names. I will send out some samples for your feedback asap. Meanwhile, you should refrain from doing too much work in switching to the names that are currently generated in CDM version 4.3.8, in case they change.

Announcing Netcdf-Java / CDM version 4.3.8 BETAWe are feature complete on this version, but there are some major changes that need your help in testing.In particular, version 4.3 is a complete rewrite of GRIB1 and GRIB2 file handling. Version 4.2 GRIB handling is wrong in a number of ways, especially table handling for non NCEP files, and time interval coordinate handling. If you are using CDM or TDS to read GRIB files, you want to upgrade as soon as possible. If you are running a nuclear power plant with GRIB files, please immediately do an emergency shutdown and remain offline until you can inspect.If you are depending on the CDM/TDS to read GRIB files, you must upgrade to 4.3 AND closely examine the output of any files that you really care about. Check parameter names and everything else against the original documentation if possible, especially if there is any local parameter use. Please send us any files you suspect might be incorrectly read by the CDM library. Note that we will not backport fixes to version 4.2. Note that the variable names in 4.3 will be different from those in 4.2.Evolving documentation for GRIB is at:http://www.unidata.ucar.edu/software/netcdf-java/formats/GribTables.htmlIn addition to GRIB files, version 4.3 also: 1. handles the CF calendar attribute (http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.6/cf-conventions.html#calendar) 2. allows a new syntax for calendar dates (http://www.unidata.ucar.edu/software/netcdf-java/CDM/CalendarDateTime.html) 3. implements the official version of the CF 1.6 Discrete Sampling Geometries (http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.6/cf-conventions.html#discrete-sampling-geometries) 4. supports client side certificates in OPeNDAP 5. has functioning maven builds, with refactored modules 6. has complete source at https://github.com/Unidata/threddsIf you need any of this, please test and give feedback now, while there is time to make changes. TDS version 4.3 (beta) will also be available shortly, but its much easier to test things with CDM and ToolsUI than in the TDS.Thanks, John _______________________________________________ netcdf-java mailing list netcdf-java@xxxxxxxxxxxxxxxx For list information or to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/
