Ceilometer CL61 for Cloud Measurement in Antarctica

This case study details the use of the Ceilometer CL61 by the Italian National Agency for New Technologies, Energy and Sustainable Economic Development to enhance cloud measurement capabilities in extreme polar environments. The study outlines the challenges faced in cloud research, particularly in the Antarctic region, where traditional measurement methods are hindered by harsh weather conditions and limited operational periods. The CL61 combines standard ceilometer measurements with advanced depolarization technology, allowing for improved differentiation of cloud phases and types. Researchers have reported significant advancements in understanding cloud formation and characteristics, including the detection of supercooled liquid clouds. The instrument's reliability and low maintenance needs make it a cost-effective solution for continuous in situ measurements, even during the station's closure. The findings demonstrate the CL61's effectiveness in providing critical atmospheric insights, thereby supporting climate research initiatives in challenging environments.
