Our research focuses on the vertical transport of aerosol particles, and the properties of these aerosol particles in dependence on relative humidity. For this, we use the synergy of Raman and Doppler lidar systems operated during the Land-Atmosphere Feedback Experiment (LAFE) (see https://www.arm.gov/research/campaigns/sgp2017lafe).

We will present our first results of investigating the aerosol flux. For this, we use the aerosols backscatter coefficient and vertical wind velocity collected with Raman lidar and Doppler lidar.

The LAFE project was executed at the Southern Great Plains (SGP) site of the Atmospheric Radiation Measurement (ARM) program in August 2017 in the USA.  In addition, data collected at the Land-Atmosphere Feedback Observatory (LAFO) at the University of Hohenheim, Germany is used. Results of the combined aerosol backscatter measurements with water-vapor and temperature lidar measurements to detail insights into the relative humidity dependencies on the growth of aerosols.
