We have made the decision to remove the AAM and GWO products from PSD website. These were research products, and the scientist who supported the pages has retired. We have no one currently at PSD who can support this activity.
You can access the code via this ftp link, however we cannot support the code in any way.
For those wishing to develop their own AAM products, these papers may be helpful:
