The high latitude oceans are problematic for satellite estimations of precipitation due to the high frequency of occurrence of light drizzle and snowfall. Microwave radiometric observations are sensitive to integrated cloud water path but lack skill in distinguishing precipitation onset from cloud water and cloud ice due to radiation scattering. Precipitation radars to date have lacked sensitivity to drizzle and cloud radars have suffered from both the uncertainties inherent in Z-R relations and poor sampling due to nadir-only scans. This study optimally combines coincident active and passive microwave observations from CloudSat’s Cloud Profiling Radar (CPR) and the Advanced Scanning Microwave Radiometer (AMSR2) to resolve cloud and hydrometeor distribution parameters and to force consistency between the two independent sets of coincident observations. The result is an estimation of drizzle frequency and intensity that are consistent with both the CPR and AMSR2 observations for the high latitude oceans. This study finds that zonal means of retrieved high-latitude drizzle below 0.25 mm hr-1 from these combined observations (0.263 mm day-1) falls slightly above those of CloudSat estimates (0.244 mm day-1), provided by the 2C-RAIN-PROFILE and 2C-SNOW-PROFILE products (Lebsock, 2018; Wood and L’Ecuyer, 2018), and far below that of radiometer-only estimates (0.920 mm day-1) provided by GPROF (Kummerow et al., 2015).
