[ncl-talk] A problem related to int2p_n_Wrap

[Rick Brownrigg]

Hi,

I don't know for certain what's going on, but my best guess is that out of
the 84 monthly timesteps, there 9 months that either don't have values for
the variables "pres" or "cal".  The messages are just warnings -- does this
materially affect your calculations.  If you need to detect these case and
do something different, you might try something like:

       if (any(ismissing(pi)) .or. any(ismissing(xi))) then
              ; do something different.....
              ; perhaps something like:    extnew(t,:,j,i) = extnew@
_FillValue
       else
                extnew(t,:,j,i) = int2p_n_Wrap (pi,xi,po,1,0)


Hope that helps...
Rick
