Histograms of Arecibo World Days Measurements and Linear-H Fits Between 1985 and 1995

Abstract

This document presents histograms of linear-H model fits to electron density profiles measured with the incoherent scatter radar of the Arecibo Observatory in Puerto Rico during the World Days between 1985 and 1995. The linear-H model is a four-parameter analytical function, which is shown to fit the measured electron density profiles with better than 10% accuracy. The histograms show the distribution of the four model parameters as well as statistical measures of the model errors. In addition, the report presents histograms of electron temperature, ratios of electron and ion temperatures, and line-of-sight ion velocities at 589 km. The histograms characterize the ten years of Arecibo World Days, effectively showing a climatology of the actual ranges of both model and topside parameters.
