Mixed-phase stratiform clouds are modelled for radiative transfer at 89 and 157 GHz. The ice water content (IWC) distribution in a vertical section of such a system is estimated from radar measurements. Aircraft microphysics and radar data are combined to derive parameterizations for the liquid water fraction and for the variation in ice density as a function of hydrometeor size. The effect of the reduction of ice density on the refractive index and hence the single particle extinction parameters is calculated using two different approaches which produce significantly different extinction behavior. Using aircraft-measured dropsize distributions from a range of altitudes, the ice extinction parameters are then represented as functions of IWC and temperature. The effectiveness of the parameterizations is tested by populating an Eddington model using the radar data and comparing the downwelling output brightness temperatures at the bottom of the mixed phase layer with simultaneous airborne radiometer measurements.
