| Popis: | International audience; Usefulness of radio occultation measurement by small satellites is investigated by observing system simulation experiment (OSSE) of the Venus data assimilation system. Idealized observations are prepared by French Venus Atmospheric GCM (LMD/VGCM) in which cold collar is realistically reproduced. The reproducibility of cold collar is tested by several types of observations. Results show that cold collar is successfully reproduced at least 6 hourly 3 vertical temperature profiles in the polar region. Therefore, radio occultation measurement by three satellites in polar orbits would be promising to reproduce cold collar. |
