Re: extract data according temperature level

You might take a look at NCL's "where" function:

  http://ncl.ucar.edu/Document/Functions/Built-in/where.shtml

Assuming you have an array "x", perhaps something like this is what you
want?

 x = *where*(x.le.0 .and. x.ge.-20, x, x@_FillValue)


Hope that helps...
