Wind fields observed with foil chaff technique in the mesosphere and lower thermosphere (80-98 km in altitude) by means of two micro-rockets at 1200 and 1315 UT on 14 January 1997 from Uchinoura, Japan (31N, 131E) are compared with the winds simultaneously observed with the MU radar (MUR; 35N, 136E) and the Yamagawa MF radar (MFR; 31N, 131E). The chaff and MFR results showed good agreement at 80-88 km, and MFR data were missing at higher altitudes. A coherent structure was commonly detected in the chaff, MFR, and the MUR winds, likely caused by a large scale gravity wave.
