Short summary
Ground-based observations show a phase shift in semi-annual variation of excited hydroxyl emissions at mid-latitudes compared to those at low latitudes. This differs from the annual cycle at high latitudes. We found that this shift in the semi-annual cycle is determined mainly by the superposition of annual variations of T and O concentration. The winter peak for emission is determined exclusively by atomic oxygen concentration, whereas the summer peak is the superposition of all impacts.
