[ncl-talk] Wondering Why I Get This Error

[Barry Lynn]

The where statement did the trick for *that* problem -- thank you.

If you want to check the elements of an array of any dimension and replace
that element with a scalar of the same type, then consider the where()

Statement:



Dbz = where(dbz.lt.0.0, dbz+256.0,dbz)


Is there a similar approach for adding two numbers to the array?


dbz = dbz*0.5 - 0.33


Thanks -- this should be the last of my questions abou this.
