We combine Helios spacecraft photometer brightnesses, in situ plasma densities, and interplanetary scintillation (IPS) velocity data to obtain a global description of solar wind changes. We Ðnd an increase of solar mass Ñux at solar maximum from the photometer brightnesses larger than would be expected from the usual assumption of invariant momentum Ñux over solar cycle 21 (1975-1986). A portion of this excess mass is related to solar mass ejections, which have an occurrence rate that follows the solar activity cycle.
