We have computed global He + escape fluxes for a range and a variety of diurnal, seasonal, universal time, and solar activity geophysical conditions. We average over the short‐term variables and compute the globally averaged escape flux for a range of cutoff latitudes, which separate regions of open and closed field lines, during one solar cycle. The global escape flux averaged over a solar cycle was computed, and we find that a cutoff latitude of about 60° or lower is sufficient to balance the outgassing from the Earth's crust.
