Ionospheric structure and the generation of auroral roar
Ionospheric electron density data from the Sondrestrom incoherent scatter radar (ISR) have been used to characterize the structure of the F region ionosphere during ground-based LF/MF/HF receiver observations of natural ionospheric radio emissions known as auroral roar. In five out of six cases, the F region ionosphere has significant horizontal Ne gradient scale lengths (IVN/NI mi• < 120 km, m...
متن کاملLatitudinal dynamics of auroral roar emissions
Auroral roar, a narrowband (Sf/f < 0.1) emission near 2 and 3 times the ionospheric electron gyrofrequency (2f• and 3f•), is observed with a meridional chain of LF/MF/HF radio receivers located in northern Canada spanning 67 ø to 79 ø invariant latitude. Observations of these emissions are compared with the auroral electrojet location inferred from the Canadian Auroral Network for the OPEN Prog...

متن کاملFurther evidence for cosmological evolution of the fine structure constant.
We describe the results of a search for time variability of the fine structure constant alpha using absorption systems in the spectra of distant quasars. Three large optical data sets and two 21 cm and mm absorption systems provide four independent samples, spanning approximately 23% to 87% of the age of the universe. Each sample yields a smaller alpha in the past and the optical sample shows a...
متن کاملFurther observations on the fine structure of the cornea.
A summary of the fine structure of presumably normal cornea is presented and is augmented by details not previously published. Certain differences noted between epithelial and endothelial cells are discussed, in view of their possible bearing on the function of these layers. Corneal tissue obtained from patients afflicted loith keratoconus, cornea guttata, or Wilsons disease is compared with no...
