This presentation will focus on the wind observations from both DAWN and Aeolus, as well as from Yankee Environmental Systems (YES) Dropsondes that were also part of the campaign. We will utilize the final DAWN and dropsonde data sets from the NASA DC-8 campaign and the most current Aeolus Level 2B data products.
During the approximate 45-60 minute and ~600 km long underflights of Aeolus, DAWN provided vertical profiles of the horizontal wind every 5 km from as high as 11-13 km. Up to 10 dropsondes were also deployed during these underflights. The profile comparisons between DAWN and the Dropsondes will be presented. Our main focus will be on the comparison between the wind measurements from DAWN and the Aeolus ALADIN lidar. The horizontal wind components of the DAWN profiles are used to compute a DAWN Aeolus projection of HLOS (Horizontal Line-Of-Sight) velocities. These HLOS winds are compared with the Aeolus HLOS at individual Aeolus profile locations and also integrated to match the ~85KM horizontal resolution of the Aeolus Level 2B product. These comparisons will be presented and discussed as will their impact on the design of future Cal/Val experiments.
