Summary Day‐side lunar electromagnetic transfer function estimates of Hood, Herbert & Sonett are analysed using the linearized inverse theory of Backus & Gilbert. A smooth conductivity distribution exponentially increasing with depth in the range 260‐1200 km is found to fit the data. The conclusions are compatible with the forward model calculations of Hood et al. Further calculations explore the compatibility of a silicate or metallic lunar core with the data. A metallic lunar core of radius 438 km is allowed but not required.
