We provide evidence of the influence of planetary waves on the intensity variations of the 557.7-nm airglow emission. The comparison relies on simultaneous measurements at four different stations located between 37¿N and 56¿N in latitude, 36¿E and 3¿W in longitude: meteor wind observations in France and USSR and optical measurements at 557.7 nm in France and Spain, in July 1971. An oscillation of period near 2 days had been identified in the wind data; it is also apparent on the nightglow intensity variations. Its characteristics are well accounted for by the first symmetric mode of the 52- hour period planetary oscillation of horizontal wave number 3, described previously (Glass et al., 1975). A 4¿1 hour period gravity wave apparently present in the data of the French stations is discussed.
