VACT Initial Release, July 2003

FSL has just released version 0.0 of the VACT. The focus of this delivery was to train the participating agencies (VAAC, AVO and CWSU) on the abilities of the VACT in order to establish a user feedback loop that will drive development efforts in creating a more useful tool. The FXC and AWIPS components of the VACT were enhanced to include satellite volcanic ash dispersion model displays, volcano locations, jet routes, and flight information areas for Kamchatka and the Aleutian Islands.
