CL51
High-range ceilometer for cirrus clouds up to 13 km
A high-range ceilometer designed to measure cirrus clouds up to 13 km without missing the low and middle layers, with backscatter profiling up to 15 km. The same second-generation single-lens optics as the CL31, with fully automatic 24/7 operation in all weather conditions.
