CDAT Update

The Community Data Analysis Tools (CDAT) is a feature rich set of various tools designed to support an array of data analysis and visualization applications. While supporting a wide set of applications, CDAT is also designed specifically to support the Earth System Grid Federation (ESGF) scientific community and provide specialized capabilities for accessing and performing various analysis and visualization operations on climate data. Some of the main packages included in CDAT are: CDMS (Community Data Management System) and VCS (Visualization Control System). CDMS is an object-oriented data management system specialized for organizing multidimensional, gridded data used in climate analysis and simulation. VCS provides 2D and 3D graphical plotting capabilities to the scientific community and allows wide-ranging changes to be made to the data display, provides for hardcopy output, and includes a means for recovery of a previous display.
