Scientific paper

The properties of the integrated intensity and velocity variations of the solar gravity modes in the 40 to 130 microHz frequency range are given in the adiabatic and nonadiabatic case. Grey atmosphere and Eddington approximations have been used as a first step. Equipartition of the energy has been assumed in order to give an estimation of the amplitudes. For integration over the whole disk, low degree models l = 1, 2 have the highest amplitudes due to the spatial filtering, but a decrease of this amplitude appears in the range 60 to 80 microHz due to the intrinsic properties of the waves.
