State of the Art Remote Sensors

ESA reference LIDAR that mimics the operation of the spaceborne LIDAR ALADIN

Validation of the Aeolus mission

eVe LIDAR aims to provide the ESA-Aeolus mission with a flexible, mobile reference ground-based LIDAR system capable of providing well-characterized fiducial reference measurements of aerosol optical properties 

The ground-truth for ESA – Aeolus aerosol retrieval

Dual-laser/dual-telescope configuration.

It enables the simultaneous emission of linearly and circularly polarized radiation at 355 nm and the detection of the elastically backscattered radiation with polarization sensitive channels, as well as the inelastic (Raman) backscattered radiation at 387 nm

Upgradability to support future EarthCARE satellite observations.

eVe LIDAR can be upgraded to multi-wavelength system to support calibration/validation activities of the ATLID LIDAR on-board the EarthCARE satellite

Advanced Algorithms

The processing algorithms will provide the attenuated backscatter, circular and linear depolarization ratios,
backscatter coefficient and extinction coefficient at 355 nm, including the associated uncertainties

ALADIN detects only the co-polar component of the backscattered circularly polarized radiation.

A portion of the received radiation gets lost, leading to an underestimation of the backscatter coefficient and the circular depolarization ratio in strongly depolarizing scenes with non-spherical particles
The main focus of the new eVe LIDAR is to quantify these uncertainties and to evaluate aerosol backscatter/extinction retrievals for Aeolus, and later also for EarthCARE product validation, quality assessment and improvement
