DOI: 10.1016/j.asr.2018.12.011

Abstract: Abstract The deviation of the IRI estimates of the monthly mean foF2 in the low mid latitude of 95°E–130°E longitude sector is investigated using simultaneous ground measurements at four stations during 2010–2014. The stations form… read more here.

Published in 2019 at "Applied Sciences"

DOI: 10.3390/app9142782

Abstract: The critical frequency foF2 of the ionosphere F2 layer is one of the most important parameters of the ionosphere. Based on the Elman neural network (ENN), this paper constructs a single station forecasting model to… read more here.

Published in 2020 at "Entropy"

DOI: 10.3390/e22040442

Abstract: It is critically meaningful to accurately predict the ionospheric F2 layer critical frequency (foF2), which greatly limits the efficiency of communications, radar, and navigation systems. This paper introduced the entropy weight method to develop the… read more here.
