RT Journal Article ID 40b5dcf3762c0791 A1 Fedorenko, Alla K. T1 ENERGY OF ATMOSPHERIC GRAVITY WAVES AS DETERMINED FROM IN SITU SATELLITE MEASUREMENTS JF Radio Physics and Radio Astronomy JO RPRA YR 2011 FD 2011-02-24 VO 2 IS 1 SP 37 OP 45 K1 atmospheric gravity waves K1 satellite measurements K1 potential energy K1 atmospheric gas components K1 thermobaric energy K1 acoustic energy AB A technique is suggested for determining spatial energy density distribution of Atmospheric Gravity Waves (AGW) from direct satellite measurements. The technique is capable of estimating the potential energy of the waves using either of the two kinds of satellite data, which are 1) mass-spectrometer measurements of concentrations of the atmospheric gas species and 2) synchronous measurements of the total density and temperature. The distribution of the potential energy components, acoustic and thermobaric ones, as obtained for AGWs observed from the Dynamics Explorer 2 satellite is analyzed. Several kinds of AGWs, with respect to the energy proportions, are identified at altitudes of the F2 ionospheric region. These are polar waves with nearly equal amounts of the two potential energy components, middle latitude and low latitude ones which are characterized by the prevailing amount of the thermobaric energy and nearly equal levels of the potential energy. The maximum energy density of AGWs is observed in polar regions. PB Begell House LK https://www.dl.begellhouse.com/journals/6fd1549c0e2c05da,059550b43d2daa52,40b5dcf3762c0791.html
