Micro Pulse LiDAR: A Multiple Perspective View of Our Atmosphere
Hosted By: OSA Laser Systems Technical Group
11 December 2019, 14:00 – 15:00
As extreme weather events become the norm, actively measuring and tracking clouds and aerosols will provide insights for understanding the atmospheric structure and uncovering changes that have an impact on our environment and health. Micro Pulse LiDAR (MPL) instruments deliver a vertical profile of the atmosphere, including cloud height for Planetary Boundary Layer studies, and measurements of particle depolarization, for detecting aerosol physical properties and cloud phases.
In this webinar hosted by the OSA Laser Systems Technical Group, Dr. Yunhui Zheng of Hexagon US Federal will explain the science behind this type of atmospheric LiDAR. As part of the webinar, Dr. Zheng will share the principle and benefits of an aerosol LiDAR for atmospheric research as well as discuss how backscattering LiDAR provides a rich source of atmospheric feature information. The webinar will also cover the application of attenuated backscattering, depolarization, and aerosol classification as well as how to interpret the resulting data. Finally, a quick walk through of accumulated sample data, which includes aerosol/boundary layer evolution, cloud height/phase detection, precipitation process observation, dust/volcanic ash/pollen detection and identification will be presented.
Register now to understand why this technology is necessary for weather forecasting, climate modeling, and environmental monitoring.
What You Will Learn:
- LiDAR principals
- How backscattering LiDAR works
- How others have applied this technology
Who Should Attend:
- Those interested in atmospheric remote sensing, air quality monitoring, meteorology, LiDAR applications, and photonic detection
