1.Laser ceilometer product overview

Laser ceilometer utilizes meterscatter lidar technology to automatically and continuously monitor the height of the cloud base for meteorological and aviation applications.Laser ceilometer is a backscattering lidar using the meter scattering principle.The observation range can reach 12 kilometers, and can effectively measure aerosols, cloud height, cloud thickness, cloud cover and vertical visibility, etc.It can be applied to complex aerosol research or integrated into large observation networks.It is a representative solution to the current highest technical level for the diverse needs in atmospheric research.

2.Laser ceilometer function application

Aerosol vertical profile, cloud base height (5 layers), cloud thickness, vertical visibility, boundary layer height

Among them, the extended type has better performance for mixed layer measurement and aerosol research.

3.Working principle of Laser ceilometer

According to the meter scattering principle, by measuring the backscattering signal profile of the emitted infrared beam by the atmosphere, we can determine whether there are clouds in the direction of the light path, and calculate the cloud base height, cloud penetration thickness, aerosol extinction coefficient, sky-atmosphere boundary layer height, Vertical visibility is output when the sky is blurred, and cloud cover can be statistically estimated by establishing a time series of cloud base heights.

This equipment uses advanced infrared laser remote sensing technology, with accurate cloud base height measurement, rich data products, stable and reliable operation, and simple use and maintenance.

4.Laser ceilometer product features

1.Using meter scattering laser technology, the signal transmission power is powerful and stable, and the measurement distance is long.

2.The equipment has penetrating measurement capabilities and can simultaneously measure multi-layer cloud and aerosol data.

3.Use highly sensitive optical components to obtain high-precision measurement results: The optical design enables the application of narrow-band filters, effectively suppresses optical effects, and enables accurate measurement of clouds and aerosols during the day and night.

4.Dual-lens design allows for self-inspection between lenses to minimize the impact of lens contamination.It is not easily affected by diffuse reflection of particles in the atmosphere and has high sampling accuracy, reaching 5m.

5.Reliable operation around the clock, equipped with a sealed metal shell and automatic window heating system, and is not affected by fog, rain, or freezing.

6.Friendly operation interface and ease of use, simple maintenance and no consumable parts.
