Planetary Boundary Layer

LIDARs with high spatial and temporal resolution can monitor and sense the PBL with tremendous detail using aerosols as tracers

PBL is subject to direct earth-atmosphere influence because of its proximity to the surface of the earth

 

Surface friction, terrain, and solar heating all influence, to various degrees, the part of the atmosphere closest to the surface, leading to mechanical turbulence, convective activity and variation in wind direction and speed

PBL
In this layer physical quantities such as flow velocity, temperature, and moisture display rapid fluctuations (turbulence) and vertical mixing is strong

 

Looking into the PBL with Raymetrics 3D scanning LIDARs

Validating Forecast Models

The ability to detect aerosol in lower altitude is improved by the deployment of scanning LIDAR. Using a 3D scanning aerosol LIDAR in particular, can provide excellent information on the mixing height, up and down drafts, and aerosol loading

Raymetrics 3D Ceilometer Data

  • Vertical mixing layer height
  • Horizontal scanning allows tracking and monitoring of aerosol plumes in urban environments
  • Spatial variation of PBL height is observed by the scanning LIDAR
  • The scanning LIDAR provides the multi-dimensional views of aerosol and clouds
