Ozone LIDAR

Ozone is one of the most important trace components in the earth's atmosphere. High concentrations of ozone in the stratosphere absorb most of the ultraviolet rays from the sun to prevent the earth from being harmed whereas Tropospheric ozone is a greenhouse gas and a pollutant detrimental to human health and plant growth.

CAS-O3-LIDAR is a Ozone LIDAR (Light Detection and Ranging) product self-developed by  Hefei CAS-Environmental Optical Technology Co., Ltd., which is jointly constituted by  Chinese Academy of Sciences Hefei Institutes of Physical Science and Chinese Academy of Sciences Anhui Institute of Optics and Fine Mechanics.

The Ozone LIDAR is based on the principle of DOAS (Differential Optical Absorption Spectroscopy) to measure vertical ozone concentration. It emits two lasers of different wavelengths into the atmosphere. One of the wavelengths is located at strong ozone absorption while the other wavelength focuses on a location where ozone absorption is weak. The atmospheric ozone concentration is determined using the differential absorption of these two wavelengths.

Product advantages

• Optimized differential wavelength pair (290nm/295nm) with high ozone detection sensitivity and less interference from aerosols;
  
• Quantitative analysis of horizontal and vertical ozone transmission using three-dimensional assimilation;
• Brand new solid-state stimulated Raman laser technology with more compact system and air-tightly protected light source;
• Independently controllable, lower maintenance costs and faster response of core components such as lasers thanks to self-development and self-production;
• Lower power consumption for the air-cooled laser, making the LIDAR suitable for under cold, vehicle mounted, plateau and other harsh conditions;
• Smooth switching between mobile monitoring, vertical observation, scanning observation and other application scenarios.
