作为犹他州立大学全球电离层测量同化（GAIM）项目验证项目的一部分，利用大型TOPEX总电子含量（TEC）测量数据库对新改进的电离层预测模型（IFM）进行了系统验证。用于验证的TOPEX数据为1992年8月至2003年3月期间，18 - s平均数据总数接近1100万。该模型验证工作涵盖了广泛的季节（冬季、夏季和春分）和太阳（低F10.7、中值F10.7和高F10.7）条件，以及所有UT变化，重点是非风暴时间TEC。验证结果表明，IFM TEC的空间分布特征与TOPEX TEC的空间分布特征有系统的一致性。在几乎所有的位置和条件下，IFM TEC和TOPEX TEC之间的差异在20%以内。在许多情况下，差异甚至低于10%。
As a part of the validation program in the Utah State University Global Assimilation of Ionospheric Measurement (GAIM) project, a newly improved Ionosphere Forecast Model (IFM) was systematically validated by using a large database of TOPEX total electron content (TEC) measurements. The TOPEX data used for the validation are for the period from August 1992 to March 2003, and the total number of 18‐s averaged data is close to 11 million. This model validation work covers a wide range of seasonal (winter, summer, and equinox) and solar (low‐F10.7, median F10.7, and high‐F10.7) conditions as well as all UT variations with the focus on nonstorm time TEC. The validation results indicate that the features of the spatial distribution of the IFM TEC are systematically consistent with those of the TOPEX TEC. The differences between the IFM TEC and the TOPEX TEC are within 20% for almost all locations and conditions. For many conditions, the differences are even below 10%.
