摘要

本文给出了与IRI-2016模型比较的f2层(Vz-hmF2)等离子体垂直漂移速度。Vz-hmF2数据来自泰国Chumphon (Lat. 10.72°N, Long. 99.37°E, Dip 3.0°N)赤道电离层探空站。分析了2010年太阳低活动期Vz-hmF2的日变化和月变化。结果表明，IRI-2016模式高估了正午至午夜的观测Vz，而低估了日出前至正午时段的观测Vz。观测到的Vz变化范围为-60 ~ 110 m/s，模型变化范围为$\pm ~ $ 20m/s。本文对IRI模型的改进具有一定的指导意义。

Vertical plasma drift velocity of F2 layer inferred from ionosonde compared with IRI-2016 Model Over Chumphon, Thailand

This paper presents the vertical plasma drifts velocity of the F2-layer (Vz-hmF2) compared with the IRI-2016 model. The Vz-hmF2 data was obtained from the equatorial ionosonde station at Chumphon (Lat. 10.72°N, Long. 99.37°E, Dip 3.0°N), Thailand. The Vz-hmF2 during low solar activity in 2010 was analyzed the daily and monthly variations between both the observed and the modelled. The results show the IRI-2016 model overestimates the observed Vz during noontime to midnight while it underestimates from pre-sunrise to noontime hours. The observed Vz changes from -60 to 110 m/s and the model varies between $\pm 20m/s$. This paper will be helpful the improvement of the IRI model in the future.
