TL;DR: In this article, the authors used five years of measurements on board the ROCSAT-1 satellite to develop a detailed quiet time global empirical model for equatorial F region vertical plasma drifts, which describes the local time, seasonal and longitudinal dependence of the vertical drifts for an altitude of 600 km under moderate and high solar flux conditions.

TL;DR: In this paper, the authors performed numerical simulations for the 29-30 October 2003 superstorm period in the American longitude sector (∼ −70°W) using the Sheffield University Plasmasphere Ionosphere Model (SUPIM) with values for the neutral wind, temperature, and composition provided by the National Center for Atmospheric Research (NCAR) Thermosphere General Circulation Model (TIEGCM).

TL;DR: In this article, the global distribution of the occurrence rate for density irregularities at 600 km topside ionosphere between ±35° geographic latitudes has been studied with the ROCSAT data during moderate to high solar activity years of 1999 to 2004.

TL;DR: In this article, the seasonal and longitudinal dependent equatorial F region disturbance vertical plasma drifts were determined from the ROCSAT-1 satellite, and the largest prompt penetration drifts near dusk and dawn occurred during June solstice.

TL;DR: In this article, the authors used a linear regression analysis between the vertical drift velocity and the irregularity occurrence rate to find the best spatial/temporal distribution in existence so far and fill the gap of irregularity distribution missing over some eastern Pacific region where no ground observation is available.
