[ncl-talk] how to plot divergent winds, divergence and velocity potential in one single plot?

[Guido Cioni]

Hi,
This error usually pops up when you're doing assignment that delete the original attributes of the variable, including the reference to the coordinate variables. 

I'm just speculating but...could it be this line? 

    plot1 = gsn_csm_vector_map(wks,0.001*ud(0,0,:,:),0.001*vd(0,0,:,:),vcres)

You are doing 0.001*ud(0,0,:,:), so merely assigning a new variable without copying the attributes.
You should instead do the scaling first 

ud=0.001*ud(:,:,:,:) ; here the attributes are preserved

and then plot ud(0,0,:,:).
Or just a define a new variable based un ud first. 

Let us know whether that works, that's the first thing that comes to my mind.
