The predominant background disturbance on a long‐period vertical seismograph is removed by providing compensation for atmospheric pressure fluctuations. A seismically‐compensated, long‐period microbarovariograph for study of pressure oscillations in the range 20–2000 sec is described. Comparison of records from the pressure‐compensated seismograph and the seismically‐compensated microbarovariograph indicates that no significant ground motion is caused by direct coupling of atmospheric pressure fluctuations to the Earth. Sample records are shown.
