Hi,
I think example 1 will deal with your problem on how to weight data,
http://www.ncl.ucar.edu/Applications/eof.shtml.
For example:
; =================================================================
; create weights: sqrt(cos(lat)) [or sqrt(gw) ]
; =================================================================
rad = 4.*atan(1.)/180.
clat = f->lat
clat = sqrt( cos(rad*clat) )
; =================================================================
; weight all observations
; =================================================================
wSLP = SLP ; copy meta data
wSLP = SLP*conform(SLP, clat, 1)
wSLP@long_name = "Wgt: "+wSLP@long_name
; =================================================================
I hope this helps.
