A method (500) for determining a sonde error in a logging tool comprising a transverse or triaxial array includes obtaining a first measurement (501) using the array while the logging tool is at a first height from ground in a selected orientation; obtaining a second measurement (501) using the array while the logging tool is at a second height from the ground in the selected orientation; deriving a difference measurement (503) from the first measurement and the second measurement; determining a background signal (508) using the difference measurement and a predetermined function (506), wherein the predetermined function relates earth signals in a plurality of signals obtained at the second height to a plurality of difference signals between signals obtained at the first height and the second height at a plurality of formation conductivities; and determining the sonde error by subtracting the background signal from the second measurement (507).
