Abstract:
Radial velocity measurements collected by the airborne radar RASTA during HyMeX SOP-1 are used to assess the quality of real-time multiple-Doppler winds produced in southern France from six ground-based radars of the French operational radar network ARAMIS. An original verification procedure based upon the exploitation of RASTA radial velocities is proposed and applied to 10 hours of data collected during HyMeX IOPs 6, 8 and 15. The statistical evaluation of multiple-Doppler winds produced in a variety of weather situations shows that errors in ARAMIS-derived horizontal wind components are generally comprised between 0.5 and 2 m.s−1 through most of the troposphere. In a second time multiple-Doppler winds are used to evaluate the performance of 3-D wind retrieval inferred from the analysis of RASTA radial velocities collected during HyMeX IOP 8. The mean difference between the two datasets is close to nil for all three wind components suggesting that errors on multiple-Doppler and RASTA-derived 3D cloud winds should be very similar.
