Table 2.
Assimilation runs of Cases H1, H6, H24 and Vmc and free run forecast of Case Frf.
| Cases | Observations | Intervals | VAFES |
|---|---|---|---|
| H1 | Qt | 1 h | Qz |
| H6 | Qt | 6 h | Qz |
| H24 | Qt | 24 h | Qz |
| Vmc | VMC | Approximately 24 h | Qz |
| Frf | None | None | Qz |
Idealised observational data for Cases H1, H6 and H24 are prepared by the simulation run of Case Qt with different intervals: 1, 6 and 24 h. Real observational data for Case Vmc is based on the ultraviolet (UV) images captured by the Venus Monitoring Camera (VMC)15 with approximately one Earth day interval. All cases are forced with solar heating, including only the zonal mean component (which is the same setting as Case Qz), i.e. the thermal tide is excluded.
