Table 2
The simulated dataset errors and the 3CH estimated error for foF2. The mean and STD_True in the IRO column are the differences between the “true” background and the simulated IRO inversions. The mean and STD_True in the pseudo ionosonde column indicate the specified errors for the simulated ionosonde observation data, similar to the pseudo ionosonde column. The STD_3CH row is the STDs of the three datasets calculated by the 3CH method.
| IRO | Pseudo ionosonde | Pseudo IRI | |
|---|---|---|---|
| Mean(MHz) | 0.079 | −0.001 | −0.147 |
| STD_True(MHz) | 0.448 | 0.405 | 0.815 |
| STD_3CH(MHz) | 0.451 | 0.406 | 0.821 |
