INTERCOMPARISONS OF SIMULTANEOUS REMOTE AND IN-SITU WIND MEASUREMENTS

A large number of ground based, balloon and rocket borne experiments w as performed at various stations during DYANA. This allows the compari sons of simultaneous wind profiles determined by the different techniq ues. This paper briefly describes each technique and discusses the com parisons between: foil chaff at Andoya (69-degrees-N, 16-degrees-E) an d EISCAT winds data at Tromo (70-degrees-N, 19-degrees-E); foil chaff or falling sphere at Andoya and MF radar winds data at Tromso; MF rada r at Juliusruh (54-degrees-N, 13-degrees-E), meteor radar at Kuhlungsb orn (54-degrees-N, 11-degrees-E), meteorological rockets at Zingst (54 -degrees-N, 12.5-degrees-E) and LF drift winds at Collm (51-degrees-N, 13-degrees-E); falling sphere, balloons and, for the first time, a Ra yleigh Doppler Lidar at the Centre d'Essais des Landes (C.E.L. 44-degr ees-N, 1-degrees-W). These methods have widely varying altitude, spati al and temporal resolutions. Despite these differences, the comparison s show a generally good agreement.
