Development of an Atmospheric LiDAR Device for Measuring PM2.5 Vertical Distribution

 

Line Album รูปทำงาน 240611 6

Background
Atmospheric science research has shown that the density of fine particulate matter (PM2.5) in the air is influenced by various climatic factors, such as air ventilation, wind speed, and direction. One critical factor is the Mixing Height Layer within the Atmospheric Inversion Layer, which governs the dispersion of particles. This led to the design and development of an Atmospheric LiDAR device, utilizing LiDAR technology to measure the vertical distribution of PM2.5 and aerosol particles in the atmosphere.

Objectives

  1. To measure the vertical distribution of aerosols and particulate matter, including the mixing height layer.
  2. To reduce reliance on imported tools and equipment.
  3. To provide data that supports government agencies in formulating policies to manage air pollution.

Key Features

  • A prototype device for vertical measurement of PM2.5 and aerosols in the atmosphere.
  • Operates on the principle of light scattering at a wavelength of 532 nm when interacting with aerosols in the atmospheric layers.
  • Dimensions: 45 x 60 x 100 cm (Width x Length x Height)
  • Weight: 30 kg (excluding electronic components)
  • Integrates advanced astronomical and engineering knowledge for atmospheric science research.

Market Context
The MiniMPL device from Droplet Measurement Technologies uses low-energy, high-frequency laser beams at a wavelength of 532 nm to measure the height of the mixing layer and aerosols in the atmosphere.

Market Value
The MiniMPL device, including software and import costs, is valued at approximately 10 million THB.

Cost of Prototype Development:
Approximately 5 million THB.

Commercialization and Industrial Expansion
The data collected from this device can be further analyzed and integrated into forecasting models for more accurate weather predictions. Additionally, the prototype technology can be scaled up, shared through knowledge transfer, and utilized to raise awareness among youth and communities about air quality issues. This approach can foster understanding, promote preventive measures, and encourage participation in solving air quality problems in the future.
