[ncl-talk] sum

[Vanúcia Schumacher]

I would like to add (+) three variables that contain missing values, but I need that during the sum disregarding the missing value, in the same way as the sum function.
Any suggestion?



        varD = data(:,11)
        varD at _FillValue = -999.00
        varJ = data(:,0)
        varJ at _FillValue = -999.00
        varF = data(:,1)
        varF at _FillValue = -999.00

        xmean = (varD+varJ+varF)
