英文摘要 | The profiles of marine boundary layer (MBL) cloud and drizzle microphysical properties are important for studying the cloud-to-rain conversion and growth processes in MBL clouds. However, it is challenging to simultaneously retrieve both cloud and drizzle microphysical properties within an MBL cloud layer using ground-based observations. In this study, methods were developed to first decompose drizzle and cloud reflectivity in MBL clouds from Atmospheric Radiation Measurement cloud radar reflectivity measurements and then simultaneously retrieve cloud and drizzle microphysical properties during the Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) campaign. These retrieved microphysical properties, such as cloud and drizzle particle size (r(c) and r(m,d)), their number concentration (N-c and N-d) and liquid water content (LWCc and LWCd), have been validated by aircraft in situ measurements during ACE-ENA (158 hr of aircraft data). The mean surface retrieved (in situ measured) r(c), N-c, and LWCc are 10.9 mu m (11.8 mu m), 70 cm(-3) (60 cm(-3)), and 0.21 g m(-3) (0.22 g m(-3)), respectively. For drizzle microphysical properties, the retrieved (in situ measured) r(d), N-d, and LWCd are 44.9 mu m (45.1 mu m), 0.07 cm(-3) (0.08 cm(-3)), and 0.052 g m(-3) (0.066 g m(-3)), respectively. Treating the aircraft in situ measurements as truth, the estimated median retrieval errors are 15% for r(c), 35% for N-c, 30% for LWCc and r(d), and 50% for N-d and LWCd. The findings from this study will provide insightful information for improving our understanding of warm rain processes, as well as for improving model simulations. More studies are required over other climatic regions. |
