TLDR
In this paper, the authors used ionization models for phase disturbances, HF absorption and solar protons in 1967 PCA events, using ionization model, and showed that VLF phase disturbances and HF absorption are correlated.Abstract:

Precipitation of particles at low and middle latitudes
TL;DR: In this paper, the phenomenology and aeronomic effects of charged particle precipitation at middle and low latitudes are reviewed, including the behavior of quasi-trapped electrons observed at low-latitudes, and the precipitation of protons from the ring current into the lowlatitude atmosphere.

VLF propagation disturbances and electron precipitation at mid-latitudes
T. A. Potemra,T. J. Rosenberg +1 more
TL;DR: In this article, the phase disturbances to long-distance mid-latitude (2 ≲ L ≲ 4) VLF transmissions during a magnetospheric substorm on January 2, 1971, are presented.

Stratospheric mixing estimated from high altitude turbulence measurements
TL;DR: In this article, the vertical diffusion coefficients in the stratosphere were estimated from data obtained in the High Altitude Clear Air Turbulence (HICAT) investigation, and the square roots of the integrals of these spectra for wavelengths <610 m, designated vi (for the ith component of velocity), were computed and related to the dissipation of kinetic energy.

On the Use of VLF Narrowband Measurements to Study the Lower Ionosphere and the Mesosphere–Lower Thermosphere
TL;DR: In this paper, a review of the use of very low frequency (VLF, 3-30 kHz) signals generated by various natural and man-made sources for the study of the ionospheric D-region and the mesosphere-lower thermosphere is presented.
Journal ArticleDOI
The correlation of VLF propagation variations with atmospheric planetary-scale waves
TL;DR: In this article, the authors compared the received daytime phase of long distance, cesium-controlled, VLF transmissions with the height variations of the 10 mb isobaric surface during the first 3 months of 1965 and 1969.

A review of D-region processes in non-polar latitudes
TL;DR: In this article, a re-examination of three major areas of D-region aeronomy, namely, the height distribution of nitric oxide, the distribution of the effective recombination coefficient and the nature and distribution of negative ions, is presented.

Angular Distributions and Energy Spectra of Electrons Associated with Auroral Events
I. B. McDiarmid,E. E. Budzinski +1 more
TL;DR: A number of Black Brant II rockets containing various charged-particle detectors have been fired during 1963 and 1964 from Fort Churchill, Manitoba Most of the firings took place at times of auroral events and the rocket instrumentation was designed to study the particles associated with these events as discussed by the authors.

Effects of polar cap absorption events on VLF transmissions
S. Westerlund,F.H. Reder,C. Åbom +2 more
TL;DR: In this paper, the effects of polar cap absorption events on the phase and amplitude of VLF transmissions were studied for the first time, and it was shown that normalization of (Δφ) with respect to frequency and affected length leads to two distinct linear relationships between (Ά) and (log log F/F0), where F is the proton flux as measured by satellites.

Penetration of solar protons to synchronous altitude
G. A. Paulikas,J. B. Blake +1 more
TL;DR: In this article, the authors measured the solar proton fluxes in two energy intervals (5 −21 Mev and 21 −70 Mev) with detectors aboard the geostationary ATS 1 satellite during the solar Proton event that began on January 28, 1967.
