Coordinated Multiwavelength Raman Lidar/Sun Photometer Measurements

– Study influence of height distribution of aeorsol properties on aeronet retrievals

Focus on hygroscopic growth– Validation campaigns using NOAA AAO in 2009

and 2010. Joint retrieval studies

– Develop optimized retrievals for MW lidar + sunphotometer Single wavelength backscatter lidar + sun
