INNOVATIVE RESEARCH FEATURES

WALL-E emits linearly- and elliptically polarized light and detects the linear and circular polarization of the backscattered light from the dust particles in the atmosphere. It also employs scanning capabilities so as to provide more information on the dust orientation and microphysical properties. The system is designed based on the high-quality standards of the European LIDAR network EARLINET, in the framework of ERC-COG program D-TECT (https://react.space.noa.gr/)  

WALL-E measurements

  • Direct flags of dust orientation, as well as more detailed information of the particle microphysics
  • Capability to acquire measurements at varying viewing angles

State-Of-The-Art Design

The system is emitting linearly- and elliptically polarized light at 1064 nm and detecting the linear and circular polarization of the backscattered light

Data accuracy

In order to achieve good signal-to-noise-ratio in short measurement times the system is equipped with two laser sources emitting in interleaved fashion, and two telescopes for detecting the backscattered light from both lasers

Advancing the remote sensing of desert dust

The irregular shape of mineral dust provides a strong signature on active and passive polarimetric remote sensing observations. Nowadays, advanced LIDAR systems operating in the framework of ACTRIS are capable of providing quality assured, calibrated multi-wavelength linear particle depolarization ratio measurements, while new developments will provide us more polarimetric measurements in the near future
