Synergetic use of active and passive remote sensing techniques to retrieve vertical profiles of atmospheric aerosol properties during day- and night-time Benavent Oltra, José Antonio Alados Arboledas, Lucas Román Diez, Roberto Universidad de Granada. Programa de doctorado en: Física y ciencias del espacio Aerosoles Atmósfera Teledetección This PhD dissertation focuses on the characterization of atmospheric aerosols properties during day- and night-time combining active and passive remote sensing measurements. The study provides both column-integrated and vertically resolved aerosol properties. The key for this thesis is the combination of advanced ground-based remote sensing instrumentation. By one hand, it is used a multiwavelength Raman lidar that which measures both elastic and Raman signals, therefore, independent backscatter and extinction profiles can be calculated. The system operates twice a week in the frame of ACTRISE - ARLINET (Aerosols, Clouds, and Trace gases Research InfraStructure Network - European Aerosol Research LIdar NETwork) and more intensively during special field campaigns. But due to the low signal-to-noise ratio Raman measurements are only available during night-time, being the daytime measurements based on the use of multiwavelength elastic measurements. Additionally, continuous measurements during the entire year have been registered with a ceilometer in the infrared range. Finally, sun/sky photometry was used to obtain direct estimation of aerosol optical properties during daytime and lunar photometry for direct estimation of spectral aerosol optical depths during night-time. 2019-04-26T08:01:39Z 2019-04-26T08:01:39Z 2019 2019-03-29 info:eu-repo/semantics/doctoralThesis Synergetic use of active and passive remote sensing techniques to retrieve vertical profiles of atmospheric aerosol properties during day- and night-time: Universidad de Granada, 2019.
