vis5d files from ferret

[Nicolas Schneider <schneid@xxxxxxxxxxxxx>]

Dear Ferret users

I would like to use Ferret to write a Vis5D-file of atmospheric 
temperature data. Basically, I use the following command to write the file:

GO vis5d_write   dTemp_apr.v5d    DTEMP_APR

Writing of the file then also works, but when I display the data in 
vis5d+  (vis5d+-1.2.1) they are erroneous, i.e. they are upside-down. 
Instead of a positive z-axis pointing upwards (atmosphere), the z-axis 
points downwards (ocean). I also tried defining the z-axis with the 
depth qualifiyer and afterwards turning my data in Vis5d by 180°. But 
then, obviously, everythign is mirrored...

Last October, there was a similar problem in the ferret list 
(http://ferret.pmel.noaa.gov/Ferret/Mail_Archives/fu_2003/msg00743.html), 
but no reply to it. Does anyone have an idea how to correctly write my 
(atmospheric!!) data with the "vis5d_write" EF.


Thanks for any help,
Nicolas
