On Friday, March 28, 2014 the Unidata Program Center (UPC) updated the demonstration THREDDS Data Server (TDS) running on thredds.ucar.edu to version 4.5 of the TDS software. After encountering some issues with the updated version, including problems with community members' IDV bundles not loading as expected from thredds.ucar.edu, UPC staff reverted the demonstration server to version 4.3 on April 1st.
UPC staff had became aware that TDS version 4.3 running on thredds.ucar.edu was not keeping some dataset indices up to date automatically. This situation required manual intervention by UPC staff to keep the indices updated, which, coupled with changes in UPC security procedures following the intrusion on February 20, 2014, increased the urgency of releasing a new TDS version that fixed the problem. After internal testing convinced us that TDS version 4.5 was functioning properly, we followed the normal procedure of updating UPC servers (specifically thredds.ucar.edu) before releasing the package to other sites. This staged release process normally allows us to find and fix "real world" issues that are not caught by internal testing.
Version 6.11.7 of the LDM has been released. It fixes a bug that caused the NOAAPORT ingest component to crash.
Here's the story:
The NOAAPORT Satellite Broadcast System contains a lot of GRIB-2 messages. Such messages require external tables in order to be interpreted. The NOAAPORT ingest component of the LDM uses the tables that come with GEMPAK to interpret GRIB-2 messages in order to generate meaningful LDM product-identifiers. Unfortunately, not all tables are complete and creators of GRIB-2 messages are free to add data for which no corresponding table-entry exists.
Version 4.4.3 of the netCDF Operators (NCO) has been released. NCO is an Open Source package that consists of a dozen standalone, command-line programs that take netCDF files as input, then operate (e.g., derive new data, average, print, hyperslab, manipulate metadata) and output the results to screen or files in text, binary, or netCDF formats.
UCAR's COSMIC Program Office invites you to register for the Eighth FORMOSAT-3/COSMIC Data Users Workshop, to be held at UCAR's Center Green (CG1) conference facility in Boulder, Colorado, USA from 30 September to 2 October 2014.
The FORMOSAT-3/COSMIC is a joint U.S.-Taiwan mission, launched in April 2006. Since its launch, FORMOSAT-3/COSMIC has provided more than three million GPS radio occultation (RO) soundings to support research and operation. More than 1,800 researchers from 63 countries are registered users of the data.
Shortly after 0 UTC (18:00 MDT) on Saturday, March 21, 2014, the contents of the Internet Data Distribution FNEXRAD (NEXRAD Level III national composites) and UNIWISC (aka McIDAS Satellite Imagery Sectors) datastreams were updated with new products. Prior to the update, the FNEXRAD products were created on motherlode.ucar.edu and the UNIWISC products were created on unidata2.ssec.wisc.edu. Both datastreams are now being created in a 64-bit CentOS 6.5 Virtual Machine in the Amazon EC2 cloud.
Read on for a brief overview of the contents of each datastream with special emphasis on new or altered products.
A prominent Canadian researcher has discovered that the command line argument -ayfs (pronounced "aye-fuzz"), when added to Unidata's Local Data Manager (ldm) software, creates a whole new era in IT infrastructure capability and a radical paradigm shift for mobile platform deployment.
Canadian scientist Steve Emmerson, currently employed by Unidata, added the option in 1993 to the C code base, but didn't get around to trying it until April 1st, 2014. Once he tried it he found that the option creates unprecedented scalability and on-demand self-service provisioning of computer capabilities. "It seemed like a good idea at the time," said Dr. Emmerson about the switch that can be enabled at runtime, "but I had no idea that it would transform Geoscience through innovative data services and enable revolutionary ways of wringing knowledge from an ever-expanding pool of Earth System science data."
