%X This paper studies the direct effect of atmospheric loading on gravity measurements.The Newtonian attraction of a column of atmosphere can be interpreted as a Green's function.To distinguish these column load Green's functions from the more familiar point mass load Green's function of Farrell(1972),they are called atmospheric gravity Green's functions(AGGF).They are used to evaluate the contribution of global atmospheric pressure variations to local gravity.We use a more precise atmosphere model to compute AGGF with a discrete convolution method.Influences of the surface temperature,the topography around the station and the station height on gravity signals are also discussed.
