Tropospheric Delay Modeling Based on Multi-source Data Fusion and Machine Learning Algorithmserified by month, as well as the stability and efficiency. The results show that the effect of RBF is best when modeling ZTD with small-size training samples. Among them, the average RMSE of the ZTD models with RBF is 20.8?mm and 20.1?mm for two data-fusion strategies, respectively. The accuracy of

Investigation of the Characteristics of Tropopause Height Over China Using Recent RO Measurementsring the period 2015–2016, and the algorithm was the temperature lapse rate tropopause (LRT). Results showed that the distribution of the TPH is latitude-dependent. The TPH mainly concentrated in the 15.5–18?km altitude range in the southern part of China (latitude range: 0°N–33°N), whilst the TPH m

In the comparison, we can know that the good performance of radio occultation load in COSMIC-2 constellation provides richer and high-quality raw data for atmospheric boundary layer detection. More effective detection qu
