Low hygroscopic scattering enhancement of boreal aerosol and the implications for a columnar optical closure study
Zieger, Paul; Aalto, P. P.; Aaltonen, V.; Äijälä, M.; Backman, J.; Hong, J.; Komppula, M.; Krejci, R.; Laborde, M.; Lampilahti, J.; de Leeuw, G.; Pfüller, A.; Rosati, B.; Tesche, Matthias; Tunved, P.; Väänänen, R.; Petäjä, T. (2015-07-02)Ambient aerosol particles can take up water and thus change their optical properties depending on the hygroscopicity and the relative humidity (RH) of the surrounding air. Knowledge of the hygroscopicity effect is of crucial ... -
Optical and microphysical characterization of aerosol layers over South Africa by means of multi-wavelength depolarization and Raman lidar measurements
Giannakaki, Eleni; von Zyl, P. G.; Mueller, Detlef; Balis, D.; Komppula, M. (2016-07-05)Optical and microphysical properties of different aerosol types over South Africa measured with a multi-wavelength polarization Raman lidar are presented. This study could assist in bridging existing gaps relating to aerosol ... -
PollyNET - a network of multiwavelength polarization Raman lidars
Althausen, Dietrich; Engelmann, Ronny; Baars, Holger; Heese, Birgit; Kanitz, Thomas; Komppula, M.; Giannakaki, Eleni; Pfuller, Anne; Maria Silva, Ana; Preiler, Jana; Wagner, Frank; Rascado, Juan Luis; Pereira, Sergio; Lim, Jae Hyun; Young Ahn, Joon; Tesche, Matthias; Stachlewska, Iwona S. (SPIE, 2013-10-22)PollyNET is a growing global network of automatized multiwavelength polarization Raman lidars of type Polly (Althausen et al., 2009). The goal of this network is to conduct advanced remote measurements of aerosol profiles ... -
Technical Note: One year of Raman-lidar measurements in Gual Pahari EUCAARI site close to New Delhi in India - Seasonal characteristics of the aerosol vertical structure
Komppula, M.; Mielonen, T.; Arola, A.; Korhonen, K.; Lihavainen, H.; Hyvarinen, A. -P.; Baars, H.; Engelmann, R.; Althausen, D.; Ansmann, A.; Mueller, D.; Panwar, T. S.; Hooda, R. K.; Sharma, V. P.; Kerminen, V. -M.; Lehtinen, K. E. J.; Viisanen, Y. (2012)One year of multi-wavelength (3 backscatter + 2 extinction + 1 depolarization) Raman lidar measurements at Gual Pahari, close to New Delhi, were analysed. The data was split into four seasons: spring (March-May), summer ...
