    "abstract": "A possibility of geophysical measurements using the large scale laser\ninterferometrical gravitational wave antenna is discussed. An interferometer\nwith suspended mirrors can be used as a gradiometer measuring variations of an\nangle between gravity force vectors acting on the spatially separated\nsuspensions. We analyze restrictions imposed by the atmospheric noises on\nfeasibility of such measurements. Two models of the atmosphere are invoked: a\nquiet atmosphere with a hydrostatic coupling of pressure and density and a\ndynamic model of moving region of the density anomaly (cyclone). Both models\nlead to similar conclusions up to numerical factors. Besides the hydrostatic\napproximation, we use a model of turbulent atmosphere with the pressure\nfluctuation spectrum f^{-7/3} to explore the Newtonian noise in a higher\nfrequency domain (up to 10 Hz) predicting the gravitational noise background\nfor modern gravitational wave detectors. Our estimates show that this could\npose a serious problem for realization of such projects. Finally, angular\nfluctuations of spatially separated pendula are investigated via computer\nsimulation for some realistic atmospheric data giving the level estimate\n10^{-11} rad/sqrt(Hz) at frequency 10^{-4} Hz. This looks promising for the\npossibility of the measurement of weak gravity effects such as Earth inner core\noscillations.",
