For my NZAGRC work I use the computer model CenW. I have principally developed this software model, but it is freely available over the internet. Though my NZAGRC work, the model has been developed further, and publications based on the software refer to the revised model (version 4.1). The original IP plan foreshadowed that the model should continue to remain as open-source software. As part of that strategy, the next version of the model is now ready for web placement for public dissemination. 
Previous versions have been dowloadable via http://www.kirschbaum.id.au/Welcome_Page.htm. The modified web page will have essentially the same text as the current one, but the primary reference link will be changed to CenW 4.1 download instead of referring to the previous version.
