Comparison of f0F2 between observation and the prediction based on IRI-2012 over Guangzhou

  • 摘要: 利用广州台站(23.2°N, 113.3°E)的实测数据和IRI-2012模型提供的预测数据, 对比分析了2013年广州地区f0F2的变化特征. 结果表明, IRI-2012 模型能够较好预测该地区f0F2的变化趋势, 并且CCIR参数得到的预测值比URSI参数更接近实测值; 预测值与实测值存在系统偏差, 在11:00LT—06:00LT时段, 观测值均比预测值大, 其他时段则相反. 在日落后至午夜前时段, 预测值与实测值有较大差距. 绝对偏差的极值点通常出现在20:00LT左右, 最大超过4MHz. 相对偏差变化比较明显的时段是午夜后至凌晨; 在02:00LT或04:00LT及06:00LT附近, 可能会出现双误差峰值点, 最大超过0.4; 但在σ变化很大的20:00LT附近, 相对偏差却变化不大. 夜间增强现象会使得偏差增大, 导致预测值不能很好反映实测f0F2的变化.
