What's new?

The Freud is software is no longer supported, and its developer, Joe Sirott, is no longer at the institute. Freud works pretty well, but there is no support to fix the infrequent, but inevitable bugs.

(8/14/96) Version 3.2 released. If you are interested, you can look at the differences between v3.2 and the latest release (v3.1).

What is Freud?

Freud is software for visualizing climatological data sets. A graphical user interface facilitates easy display of an unlimited number of overlayed contour and vector plots. Plots can be superimposed on up to six different map projections.

Freud also allows you to:

• Interactively position an unlimited number of plots of any size at any position on a plotting page.
• Easily determine the line style, line color, fill pattern, and fill color of contours, vectors, and maps.
• Read in data in netCDF, binary, MATLAB, GrADS, or ASCII data formats.
• Browse through netCDF variable attributes.
• Create scripts to automate plots by using extentions to the fully procedural scripting language TCL.
• Save the state of the program for future reuse.

A screen dump of Freud is available here.
