Java Climate Model

Welcome to JCM5

Updated 3rd March 2006
Experimental Release

Note Feb09: Although this archived version works from jars offline, it doesn't seem to work from webstart!

Note: this version is not finished, it is put online for testing.
Please give feedback to Ben Matthews

Launch JCM5 using Java Web Start:

Java Web Start starts JCM5 as an application, with an option to use a "safe mode" where JCM5 cannot access your disk. However you must use the disk-access mode to save output, or to use the new "persistence" feature.

Webstart will cache JCM5 locally, but should automatically check for updates if you are online. (this cache may be adjusted via your "Java Control Panel" (from windows, find inside control panel).
note: if you get an error saying that the jar files are not all signed by the same key, it may be because an old copy of JCM5 remains in this cache

Note: JCM5 requires Java 5 (=1.5), it will not work with any older versions.
You can get the JRE for free from Sun at www.java.com

An alternative way to start JCM5 is to save these files to your disk:

JCM5.jar (main program: just click on this to run the model)
labdoc.jar (documentation -optional)
gcmdata.jar (regional climate data -optional)
source.jar (source code -optional)

In this case please come back soon for updates.

If you want to experiment with JCM5 source code, I recommend to install Netbeans4 together with JDK5, (free download from java.sun.com), then ask me about the current project setup.

(Old Note, maybe no longer necessary: for Mac OS 10.4+ (only), Java 5 is available from http://www.apple.com/support/downloads/java2se50release1.html)
