We analyze and compare the ionic charge composition data for different types of the solar wind which the Solar Wind Ion Composition Spectrometer on Ulysses observed during the pole-to-pole pass of its primary mission. The implications on the electron temperature, electron density and ion outflow velocity from the corresponding solar wind source regions are also discussed. We find that the electron temperature in the source region of the slow solar wind is higher than that in the coronal hole. We also find a possible north-south asymmetry in the electron temperature that may be correlated to the north-south asymmetry in the solar wind speed found in the SWOOPS/Ulysses data. Based on our data without clear constraints from other coronal observations, it is found that the electron density may be higher, or the heavy ion outflow velocities may be lower toward lower heliographic latitude.
