Correlation Studies of Protonospheric Electron Content Over the U.S. Continent.

Abstract

Measurements of the electron content of the earth's protonosphere, N sub p, defined here as the region above the height where Faraday rotation measurements of VHF signals are significant, have been compared from pairs of stations in North America. Results of studies of N sub p and of the variabilities from the monthly mean vlaues at station pairs show a lower correlation than expected. Correlation coefficients of total electron content data taken at the same station pairs by the group-delay technique and by the Faraday rotation technique are significantly higher than those from N sub p data. The random component necessary to explain the lower than expected correlation of N sub p values is larger than the estimated data accuracy from the stations. From the available data we are unable to conclude whether or not the lower than expected correlation coefficients represent a real random component in the protonosphere having horizontal scale sizes less than 400 km.
