    Abstract

    The presence of aggregates in ice clouds may severely affect millimeter-wave radar reflectivity data from airborne side-looking observations of single ice crystals. In view of this, a technique for estimating the fraction of reflectivity due to single crystals and aggregates is proposed. The relationship between the difference reflectivity (ZDP) and the reflectivity fraction corresponding to aggregates and single crystals (ZH) is derived, and is used for hexagonal columns, plates or stellar ice crystals to estimate their fraction of the measured ZH. The remaining part of ZH is attributed to the aggregates. An example based on bimodal size distribution illustrate the technique.
