Giving CDAT a spin to version 5.0

We are busy working on a new CDAT release version CDAT - v5.0. This big release will bring several new exciting features to the CDAT community. We expect to have the 'Beta' version ready for release in October 2007. We will be releasing CDAT v4.3 in August with a small subset of features listed below.

The new features include:

- LAS CDAT interface to IPCC data
- New VCDAT - Light version
-New point and click edit capabilities in a revamped VCS canvas with GUI

- TrueType fonts
- Direct PostScript output
- NetCDF 4.0 (data compression)
- VisTrails
- New numPy will replace pyFor
- Google Earth with CDAT
- iCDAT- Adobe Flash web application
- Trac source repository, check it up!

News - LAS CDAT

Live Access Server (LAS) is a software that provides visualization and subsetting of multi-dimensional scientific data for Web users, enabling visualization, subsetting, and reformatting. On-the-fly visualization makes it possible to explore the dataset entirely within a Web browser environment. Should further analysis at the desktop be desirable subsetting allows the scientist to download small units of data that move efficiently on the Internet. Reformatting makes it simple to ingest the data into the scientist’s choice of desktop environments.

New LAS CDAT web interface enables browsing and downloading of the IPCC ESG climate model simulations data holdings through the GUI web application.

News - VisTrails

VisTrails, while originally (and solely) developed by researchers at the University of Utah that provides support for data exploration and visualization, is being applied to climate data analysis and visualization as part of the SciDAC2 Visualization and Analytics Center for Enabling Technology (VACET).

Tech Tips for beginners

Basic reading a variable from one file and saving it to another NetCDF file, also concatenating files.

This tip provides information on the basic writing data to a NetCDF file techniques. You can learn all about reading a variable from one file, operating on it and writing to another file, or reading the same variable from severeal consecutive files, concatenating the data and writing to a new NetCDF file.

Advanced Tech Tips

Reading ASCII data, creating axes and saving all to a NetCDF file.

A lot of data exist in an ASCII format, hence it is important to know how to read this data and save it to a proper NetCDF file. We will learn how to read some standard ASCII data formats, create time and other axis and save all to a NetCDF file.

News - Google Earth with CDAT

CDAT is now on a web in a new interface - Google Maps and Google Earth DATA with CDAT. It is a web server application that uses the Google Map engine to display the climate observational and model data at the IPCC Data Distribution Center.

Check it up! It's vary nice and fast!
