Seaice data

Apparently its hard to find seaice area totals on the web. Well here they are. Caveats: this isn't my data (its from MMAB), I just process it. These are *area* totals: if you care about exact amounts, you should care about the difference between area and extent; and about the difference between NASA team and Bootstrap algorithms, which will produce different results.

A picture

IDL code:

a=readfromfile('ice.area.nh')
b=readfromfile('ice.area.sh')    

plot,b(0,*)+b(1,*)/12.,b(2,*),th=2,/xs
oplot,a(0,*)+a(1,*)/12.,a(2,*),th=2,col=3

gettwogifs,out='ice.area'

I won't tell you which line is NH and SH: you should be able to guess.
