[ncl-talk] Easier, more elegant way to do: ncl where() and keepMetaData?

[Erik J. Schaffernicht]

Now, I rewrote my ncl-script because on first sight it seemed you are 
right.  But when it comes to gsn_csm_contour_map  (or somewhere else, 
there is no line number given with the warning messages)
I get these warnings:

(0)    check_for_y_lat_coord: Warning: Data either does not contain a 
valid latitude coordinate array or doesn't contain one at all.
(0)    A valid latitude coordinate array should have a 'units' attribute 
equal to one of the following values:
(0)        'degrees_north' 'degrees-north' 'degree_north' 'degrees 
north' 'degrees_N' 'Degrees_north' 'degree_N' 'degreeN' 'degreesN' 'deg 
north'

and the only thing I changed was this:

w2=sediProbab
w2=where(landAreaFrV .lt. 0.5, w2 at _FillValue, w2)
copy_VarMeta(sediProbab,w2)
sediProbab=w2

to

sediProbab=where(landAreaFrV .lt. 0.5, sediProbab at _FillValue, sediProbab)


So, what is happening there with the where()
