The ARL web server contains several meteorological model data sets already converted into a HYSPLIT compatible format on the public directories. Direct access via FTP to these data files is "hardwired" into the GUI. The data files are automatically updated on the server with each new forecast cycle. Only an email address is required for the password to access the server. The "FTP menu" is locked until the FTP process is completed, at which point a message box will appear indicating the file name that was just transferred. A special extract of the GFS forecast has been created for the Asian region that is of small size for quick transfer. The downloaded file name follows the convention: AVN{month}{day}{cycle}.
