The results are reported of the first interhemispheric model of the 7320 Å airglow covering mid‐ and low latitudes, at all longitudes. A comprehensive model of the ionosphere and thermosphere is used to compute volume emission rates as a function of altitude, latitude, longitude, and local time. Selected results are shown here to illustrate the computational capability. In particular we discuss the diurnal and seasonal variability and interhemispheric coupling of conjugate photoelectrons. The model is particularly well suited for airglow studies, and provides a valuable tool for the comparison, interpretation, and planning of spectroscopic observations made from orbiting platforms for all significant thermospheric emissions.
