Iron and sodium Doppler/temperature lidar studies of the upper mesosphere

Lidar measurements of mesospheric Fe were conducted at Urbana, Illinois, during four nights in late October 1989. The average Fe abundances, layer centroid heights and rms widths varied between 1.0-2.0 $\times$ 10$\sp{10}$ cm$\sp{-2}$, 89.0-90.5 km and 3.2-4.1 km, respectively. The peak densities of the layer near 90 km varied between 15-25 $\times$ 10$\sp3$ cm$\sp{-3}$. On three nights the formation and dissipation of three large sporadic Fe (Fe$\sb{\rm s}$) layers were observed.
