The Geosciences Probe of Discovery (GEOpod) is an intuitive, interactive application that allows users to navigate through and explore an immersive 3-D environment created from authentic geoscience data. GEOpod is built on top of Unidata's Integrated Data Viewer (IDV), leveraging its sophisticated features to import and display geoscience data in a teaching environment.
UPDATE: The GEOpod short course will not be held at the Austin AMS meering. The organizers hope to present the course in a different venue in the near future.
GEOpod was created by professors and students from the departments of Computer Science and Earth Sciences at Millersville University. They, along with Unidata Program Center IDV developer Yuan Ho, will be teaching a Short Course — Interactive Immersion Learning: Flying through data onboard the GEOpod — at the upcoming American Meteorological Society annual meeting in Austin, Texas.
A new stable release of the THREDDS Data Server (TDS), version 4.3.14, is now available on the THREDDS Data Server page. We recommend that you upgrade to the current stable version as soon as possible in all cases.
The NetCDF-Java/Common Data Model (CDM) library version 4.3.14 was released on November 20, 2012. Version 4.3 includes a complete rewrite of GRIB1 and GRIB2 file handling as well as a number of other features.
Was Hurricane Sandy a freak combination of weather systems? Or are hurricanes increasing in intensity due to a warming climate? How did this perfect storm make search and rescue so dangerous?
The Unidata Program Center's Jeff Weber is one of the scientists who looks into the causes of hurricane Sandy's behavior in the NOVA documentary Inside the Megastorm, which will air on PBS Sunday, November 18 and Wednesday, November 21.
Update: The entire documentary is available for online viewing on the PBS web site at the above link.
Members of the Unidata Program Center staff will be attending the American Geophysical Union 2012 Fall meeting, December 3-7 2011, in San Francisco. The schedule below lists specific sessions at which UPC staff will be in attendance. See the AGU Fall meeting Scientific Program for additional information on the sessions.
Unidata Program Center developer Yuan Ho, along with John Clyne of NCAR's Computational and Information Systems Laboratory (CISL), will once again be presenting a data analysis workshop at the American Geophysical Union's Fall meeting in San Francisco. The workshop will provide an overview of several of the open source software packages that are most relevant to researchers and educators in the geosciences, including Unidata's Integrated Data Viewer (IDV), NCAR's Visualization and Analysis Platform for Ocean, Atmosphere, and Solar Researchers (VAPOR), the Grid Analysis and Display System (GrADS) from the Center for Ocean-Land-Atmosphere Studies, and NCAR's NCAR Command Language (NCL).
Version 4.2.3 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.
A SAX (Simple API for XML) parser is a particular mechanism for parsing XML documents. Using a SAX parser has the advantage over the DOM-based parser in that it is not necessary to build the explicit DOM tree. On the other hand, it can be difficult to build a SAX parser because it requires management of complex state.
Combining SAX parsing with a GNU Bison generated parser is appealing because it allows the Bison parser to manage all of the state. Additionally, the .y file encapsulates the equivalent of a DTD but in a much more readable form. The combination makes using SAX parsing a lot simpler.
