Aeroso High Power lidar logbook for ACTRIS-RI National Facilities

Logbook Template for ACTRIS CARS Lidar Systems Description This repository provides a standardized Logbook Template developed within the framework of the ACTRIS (Aerosol, Clouds and Trace Gases Research Infrastructure) and implemented at the CARS facility. The logbook is designed for routine operation, quality assurance, maintenance tracking and traceability of ground based lidar systems, including high power elastic, Raman and High Spectral Resolution Lidar configurations. Its main objective is to ensure harmonized documentation across ACTRIS National Facilities and Central Facilities, supporting: traceability of instrumental changes and interventions documentation of calibration activities such as telecover tests, Rayleigh fits and polarization calibration recording of system upgrades, optical realignments and component replacements tracking of software and configuration file updates such as SCC and ATLAS versions documentation of anomalies, troubleshooting actions and corrective measures compliance with ACTRIS Quality Assurance and Quality Control procedures Scope The logbook can be used for: continuous monitoring lidars campaign based lidar systems mobile or temporary installations multi wavelength systems at 355 nm, 532 nm and 1064 nm systems equipped with depolarization and Raman channels It is compatible with ACTRIS workflows involving data processing chains such as SCC and ATLAS and supports the preparation of QA reports, certification procedures and intercomparison exercises. Structure The logbook template includes structured sections for: System identification and configuration Daily operational status Maintenance and hardware interventions Calibration activities and QA tests Software and processing configuration updates Environmental conditions and operational constraints Remarks and incident reporting Each entry is timestamped and linked to responsible personnel, ensuring full traceability in line with ACTRIS QA requirements. Purpose within ACTRIS Within the ACTRIS framework, standardized documentation is essential for: instrument certification and re certification long term data reliability cross site comparability Central Facility validation procedures support of satellite Cal Val activities The implementation of this logbook at CARS contributes to harmonization efforts across the ACTRIS lidar community and strengthens the reproducibility and transparency of aerosol and cloud remote sensing measurements.
