The WRF group is interested in making their output CF compliant. Hug the next person you see.

Unidata Program Center developer John Caron has been thinking a lot about HDF5's Dimension Scales, how they relate to netCDF's Shared Dimensions, and why data should be written with the netCDF-4 library using Shared Dimensions.

If you like that sort of thing, read on.

Version 4.2.1 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.

The Unidata netCDF group announces the 4.2.1.1 release of the netCDF C libraries. Version 4.2.1.1 includes fixes for two problems found in version 4.2.1 that we regarded as serious enough to warrant this interim release:

• A DAP performance bug in remotely accessing large files (> 2GiB) that also results in an incorrect error message on close
• An ncdump bug in CDL output for netCDF-4 string data containing characters that need to be escaped (e.g. newlines, tabs, quotes)

Students in the University of Salento's Advanced Data Management course

Climate Change research is becoming an ever more data intensive and oriented scientific activity. Petabytes of climate data are continuously produced, delivered, accessed, and processed by scientists and researchers at multiple sites at an international level. The Euro-Mediterranean Centre on Climate Change (CMCC) and the University of Salento in Italy are using equipment purchased with a Unidata Community Equipment Grant to help students study climate change issues at both global and regional (Mediterranean area) scales.

If you want to write HDF5 files directly without using the netCDF-4 library, or if you want to build a netCDF-4 compatible software layer on top of HDF5, read on.

The gritty details of what dimension scales look like at the file object level.

In case you missed it — here's a wrap-up of news from the Unidata Program Center for the month of July, 2012.

Richard Ullman of the NASA Goddard Space Flight Center's Science Data Management Branch forwards information on the following two job openings. Applications for these positions will be accepted from Wednesday, August 01, 2012 to Thursday, August 16, 2012.
