A mobile, scanning eye-safe lidar for the study of atmospheric aerosol particles and transport processes in the lower troposphere
A mobile, scanning eye-safe lidar for the study of atmospheric aerosol particles and transport processes in the lower troposphere
Abstract (English)
A high-power eye-safe scanning aerosol lidar system in the ultraviolet wavelength region is introduced for the study of the optical properties of aerosol particles and transport processes in the atmosphere, especially in the atmospheric boundary layer (ABL). This system operates with an average power of 9 W in combination with a 40-cm scanner with a speed of up to 10° s-1. A modified version of the lidar inversion algorithm is developed for the retrieval of optical properties of aerosols from scanning lidar measurements. The lidar data can be analyzed with previously unachieved temporal and spatial resolution of 0.03 s and 3 m, respectively.
Abstract (German)
Zur Untersuchung optischer Eigenschaften von Aerosolpartikeln und Transportprozessen in der Atmosphäre, speziell in der atmosphärischen Grenzschicht (atmospheric boundary layer, ABL), wird ein augensicheres Hochleistungs-Scanning-Lidarsystem im ultravioletten Wellenlängenbereich vorgestellt. Das System arbeitet mit einer durchschittlichen Leistung von 9 W in Kombination mit einem 40 cm Scanner mit einer Geschwindigkeit bis zu 10° s-1. Eine modifizierte Version des Lidar-Inversionsalgorithmus zur Rekonstruktion der optischen Eigenschaften von Aerosolpartikeln aus den Scanning-Lidar-Messungen wird entwickelt. Die Lidar-Daten können mit einer bisher nicht erreichten zeitlichen und räumlichen Auflösung von 0,03 s bzw. 3 m analysiert werden.
