  • Characterization of basic components (laser, optical and electronic parts) is performed at LiCoTest: laser beam characterization, optical and spectral characterization of lenses, filters, mirrors and fiber optics, spectroscopic  ellipsometry measurements, polarization measurements, paraxial analysis of optical systems, electronic modules synchronization, stability, response time/speed.
  • Assessment of the overall system’s performance is made by side-by-side comparison with POLIS or MUSA, which are both EARLINET reference mobile lidar systems. The availability of the two systems provides a good geographical coverage and reduces time delays between demand and supply. These systems can be used as reference for scientific lidars but also for different instruments (as ceilometers, sunphotometer or in situ measurements), both commercial and scientific.
  • Systematic quality assurance of the optical and electronic chains and fault diagnosis is performed at LiReQA. Users trained at LiCalTrain collects test files and send them to be analysed, collecting feed-backs and recommendations. This ensures a homogeneous characterization of the instruments, and identification of possible biases or instrumental problems. The procedure is applied regularly to check the long-term stability of the systems.
  • Inspection, debugging  and optimization of lidars is performed by LiCheckUnit. This installation relies on the high-level expertise of its operator to identify the cause of improper operation, and find solutions to improve the performances of the lidar.
  • Intensive training to maintain and check the calibration is provided at LiCalTrain, focusing on good practices in lidar measurements and correct application of QA tests for the assessment and optimization of the optical\electronic chains.
