Re: Problems using month_to_annual() function

It would help to have a little more information. Please insert the
following three commands just above the month_to_annual statement,
and show the full output from them:

   printVarSummary (temp_mod1_all)
   print ("Number missing = " + num(ismissing(temp_mod1_all)))
   exit

Also, what version of NCL are you using?
