N2 - Interrelationships between volume extinction coefficient (σ), ice water content (IWC), and effective radius (re), each dependent upon the particle size distribution (PSD) and temperature (T), are developed using in-situ microphysical measurements at low and midlatitudes, remote sensing data, and model results. The ratio [IWC /σ], proportional to re, increases with T. Lower values of [IWC/σ] are observed near cloud top and base than within a cloud layer, although [IWC/σ] changes more with temperature than relative height within the cloud. For equivalent radar reflectivities (Ze) below about -28 dB, the minimum detectable with forthcoming spaceborne cloud radar, [IWC/σ] is a nearly constant value. IWC increases almost linearly with σ, with a temperature-dependence noted.
