The STA-LC56 Laser Ceilometer is a Mie-scattering lidar. It adopts the Mie-scattering effect of atmospheric aerosol particles on laser to detect aerosols such as dust and cloud-fog particles in the lower atmosphere below 15km(49210ft). Compared with other scattering mechanisms, Mie-scattering features a larger scattering cross-section and stronger echo signals. Since most atmospheric aerosol particles are distributed at low altitudes, detection can be performed conveniently. The instrument is deployed for observation of cloud‑base height and integrated cloud amount in airports, ships, mobile survey vehicles, meteorological stations and other scenarios.

Operating on the laser ranging principle, the ceilometer emits periodic laser pulses into the atmosphere. The receiver captures back-scattered echo signals from clouds and the atmosphere. The processor processes and inversely calculates the received signals to obtain atmospheric extinction coefficients at different altitudes, so as to identify cloud layers and compute cloud-base height.

Main Functions
a) It can measure and display cloud base height, cloud layer thickness and atmospheric boundary layer height in real time, and output vertical visibility data under obscured sky conditions.
b) It supports multi-layer cloud detection, identifying and measuring up to 5 cloud layers, and synchronously outputting the cloud base height, cloud thickness and integrated cloud amount of each layer.
c) It is equipped with an automatic self-check function to monitor the operating status and working parameters of core components, ensuring stable equipment operation.
d) It supports parameter configuration via external terminal software and features power-off protection. All configured parameters can be permanently saved without loss after power failure.
e) The output data format fully complies with the ceilometer specifications specified in the Surface Meteorological Observation Data Dictionary, realizing standardized data output and convenient docking with meteorological business systems.
f) Integrated with intelligent automatic control functions including optical lens self-cleaning and equipment self-heating, which adapts to complex outdoor working environments.
g) Built-in data storage supports continuous recording and preservation of historical monitoring data for no less than 3 months, facilitating data review and analysis.
