Summary and Conclusions
The 1
resolution WHAM H
survey plus follow up observations of fainter diagnostic lines will provide new information about the composition, structure, and kinematics of the warm ionized component of the interstellar medium and the sources of ionization within the Galactic disk and halo. In addition, it will provide the opportunity to compare the distribution and kinematics of the warm ionized gas with other major components of the interstellar medium, particularly the H I, as well as other diffuse emission, such as the microwave background. Finally, because WHAM can spectrally resolve the Galactic emission from contaminating terrestrial emission lines, the WHAM survey will be a source of kinematic and absolute intensity information for complementary, higher angular resolution H studies carried out at lower spectral resolution.
