Region of Validity of the Two-Component Approximation
On the validity of the ambipolar diffusion assumption in the polar mesopause region
... Abstract. The decay of underdense meteor trails in the po- lar mesopause region is thought to be predominantly due to ambipolar diffusion, a process governed by the ambient tem- perature and pressure. Hence, ...
