I have signed up to use the unregistered version of Hysplit Software. I am stuck at the step of uploading meteorological data from the Ftp server (ftp://arlftp.arlhq.noaa.gov/archives). I tried to change the FTP address in the FTP setting, but it never works. I still cannot resolve this issue... Why did it fail?
Please, I need your support to know how to solve the problem.
