Abstract. The Si viii line width measurements and N e
estimates based on SUMER observations are combined
with LASCO and UVCS output to provide an overview
of its variations with height above a polar coronal hole.
From the combined dataset we find a radial dependence
of the electron density, in the range 1--2 R fi as r \Gamma8 , from
2 to 4 R fi as r \Gamma4 and then as r \Gamma2 . Combining the Si viii
