eof_1.ncl

Hello,

In the example script
http://www.ncl.ucar.edu/Applications/Scripts/eof_1.ncl, the function "sqrt"
used twice on latitude array while creating weights

 create weights: sqrt(cos(lat)) [or sqrt(gw) ]
; -----------------------------------------------------------------
  rad = 4.*atan(1.)/180.
  clat = f->lat
  clat = sqrt( cos(rad*clat) ) ; gw for gaussian grid
           ^^^^
; -----------------------------------------------------------------
; weight all observations
; -----------------------------------------------------------------
  wSLP = SLP ; copy meta data
  wSLP = SLP*conform(SLP, sqrt(clat), 1)
                            ^^^^

is it necessary ?

Thanks
Siji
