Abstract

I first review the observables and optics of interstellar seeing associated with radio wavescattering in the interstellar medium. I then describe the Galactic distribution of electron density andits fluctuations, as inferred from a number of observables, including angular and pulse broadening,diffractive scintillations, and dispersion measures. Propects for improving the Galactic model areoutlined.
