Re: [ferret_users] Vis5D wind trajectories

[guimond@xxxxxxxxxxxxx]

Hi Ansley,
 I tooled around more today with the wind trajectories and I am more 
certain that there must be something wrong with Ferret's output to 
Vis5D format.  I downloaded a FORTRAN produced file from 
WISC/SSEC/CIMSS and got the wind trajectories to work fine on my local 
copy of Vis5D.  After consulting with someone from SSEC, I rearranged 
my Ferret file to have levels in km instead of hPa with all var 
names/units correct and still the trajectories didn't work.
 I will have to go the fortran route unless there is a quick fix from 
Ferret users...
