...partial reflection observations to investigate the thermal and dynamical state of the polar mesosphere during conditions of PMSE occurrence. The authors found that peak occurrence of PMSEs corresponded with temperature lows. Further, the PMSEs are linked with the typical summer equatorward flow of mesospheri...Scientists warn of climate change risk to marine turtles
