本文介绍了厦门电离层垂直探测站的建设及初步结果.该站选用了加拿大生产的数字测高仪,利用折合偶极天线作为发射和接收天线,采用气象信息专业网和internet网络的两种传输方式,实现了数据实时传输和远程控制.利用试验观测期间获得的2007年8月份首批电离层垂直探测数据,分析发现了厦门地区电离层foF2的一些基本特征:白天foF2最大值一般出现在地方时14～16点,最大值约5～15 MHz,有较强逐日变化;夜间foF2约4MHz左右,逐日变化较小.与最新国际电离层参考模式IRI2007进行了初步对比,发现IRI2007可较好的预报出foF2的月中值,但对逐日变化较强的厦门地区电离层foF2预报能力较弱.

A new ionosonde station is constructed in Xiamen and preliminary observation are briefly introduced.At this station the Canada Advanced Digitial Ionosonde(CADI)is selected as the main equipment,and a set of folded dipole antennas and a pairs folded dipole are used as transmit and received antennas,respectively.With the internet and a special net system of CMA,the observed data is transfered to the National Center for Spaceweather in Beijing very quickly and the equipment is able to be controlled far away.By using observed data at this station during August,2008,we found that the foF2 has a pronounced daily variation,and it usually maximizes at 14～16LT with an amplitude of 5～15MHz and minimizes at 4～6LT with an amplitude of 4 MHz.The IRI2007 seems to be able to reproduce the observed medium foF2, but it fails to forecast the daily foF2 due to the day to day variability of ionosphere in Xiamen.
