Abstract

Two cases from SLOPE campaign at Granada are analyzed in terms of particle microphysical properties using novel software developed at Potsdam University. Multiwavelength Raman lidar measurements of particle extinction and backscatter coefficients as well as linear particle depolarization ratios are used as input for the software. The result of the retrieval is a 2-dimensional particle volume distribution as a function of radius and aspect ratio, from which the particle microphysical properties are obtained.

Highlights

Aerosol particles play an essential role on atmosphere and climate, and it is important to have vertically resolved information about their microphysical properties
New software developed at the University of Potsdam [2] using a 2-dimensional approach is tested applying it to measurement cases from ACTRIS-2 experimental campaign SLOPE (Sierra Nevada Lidar AerOsol Profiling Experiment)
Two measurement cases were picked from the database created during SLOPE

Summary

Introduction

Aerosol particles play an essential role on atmosphere and climate, and it is important to have vertically resolved information about their microphysical properties. E., the calculation of particle microphysical properties using only Raman lidar data and applying regularization methods [1]. New software developed at the University of Potsdam [2] using a 2-dimensional approach is tested applying it to measurement cases from ACTRIS-2 experimental campaign SLOPE (Sierra Nevada Lidar AerOsol Profiling Experiment). That campaign was carried out in Granada from May to August 2016, and was designed for gathering data useful for testing the retrieval schemes through inversion of remote sensing observations. It combined active and passive remote sensing together with in-situ measurements at several levels in the northern slope of Sierra Nevada mountain range
