摘要: Abstract Using DE2 satellite data this study investigates the position of ionospheric trough minimum. Two empirical models are developed which summarize a fairly large sample, refer exclusively to F-region trough, include positions both mid-latitude and high-latitude troughs, cover all local times, use an optimized description magnetic activity.
