[gradsusr] Facing a problem with Time derivative

[Davide Sacchetti]

vint(const(mslp,1000), q, 100) is the integrated moisture

if you want to display a time varying derivative you could use cdiff, 
otherwise, if time is fixed, suppose you would plot derivative at t=2
and suppose dtime=3h, you could:

d ( vint(const(mslp(t=3),1000),q(t=3),200)-
vint(const(mslp(t=1),1000),q(t=1),200) )/(2*3*3600)

Bye
