Here is a script using two functions. I hope this helps. Note that
this version of the stereographic projection uses a spherical model of
the earth not an ellipsoidal, and is set up for the north polar aspect
of the projection, since that appears to be most appropriate for the
kind of data you ha
Dear Roger and Barry (and rest of you)
I need this as soon as possible I think. I am working with climate

Dear all
First of all, I am sorry for all inconvinience I am causing you, but I

lat<-seq(50,90,2.5)
data<-matrix(rnorm(145*17,sd=10),ncol=17,nrow=145)
And this I wan
