Description
The observation data taken by the ionosonde at Shigaraki MU Observatory in Shiga Prefecture, Japan (34.86N, 136.11E, 385m MSL). The data include reflection height and echo power of electromagnetic waves in a frequency range of 2-18 MHz transmitted by the ionosonde. The reflection height is derived from the observed length of time under the assumption that the transmitted waves
