Comparison between temperature data detected by ICON/MIGHTI and TIMED/SABER_dataSet

In this paper, the ICON/MIGHTI and TIMED/SABER temperature datasets were compared and analyzed in the range of 90~105 km, and the mean temperature deviation and root-mean-square error of both were calculated. The distribution of monthly mean temperature deviation with altitude and latitude in different months were also analyzed to provide a reference basis for MIGHTI and SABER temperature sounding data in modeling and forecasting applications of the near-space atmosphere.

The results showed that ICON/MIGHTI and SABER temperature-sounding data can be used as references for modeling and forecasting applications. The results also showed that the ICON/MIGHTI and TIMED/SABER vertical profile detections agreed. The global mean temperature deviations with altitude were positive at 90~93 km, with a maximum deviation of approximately 2.5 K and negative at 93~105 km, with a maximum deviation of approximately 10 K. The deviation was usually higher during the day than at night.
