Abstract
Results from two popular models for the complex permittivity of liquid water were compared, as applied to radiative transfer computations in the 5-250 GHz range. Substantial differences were found in situations with cloud temperatures below 0°C. Simulations of cloud liquid water retrievals from satellite and ground-based instruments demonstrated that uncertainties in the models at low temperatures can lead to large retrieval errors
