[ncl-talk] Animate_1.ncl doubt

[Sebastian Otarola-Bustos]

Hi Mary,

Thank you very much for your help and sorry for the delay in my answer, I
was out of the city and I just return. I used a "ps" file and it works
fine. I also tried the animate_2.ncl script, but I have some doubts, what
exactly are the coordinates that are ploted?, because I was used to plot
the results showing Lat/Lon coordinates with the map projection. How can I
use Lat/Lon insted of those?  I also see that animate_2.ncl uses gsn_cme
resources, If i want to plot a vectormap, the documentation says that u,v
velocities must be 2D, but my variables have the following dimensions (
Time, Lat,Lon), there is any command to set this or I need to do this
manually?. Finally, the animate_2.ncl plot temperatures at one time(I
guess) for each pressure level, how can I get variables related to the
pressure levels.

Thank you very much in advance,
Any help would be great.
Best regards,
Sebastián.
