Airborne multiwavelength High Spectral Resolution Lidar (HSRL-2) observations during TCAP 2012 : Vertical profiles of optical and microphysical properties of a smoke/urban haze plume over the northeastern coast of the US
Mueller, D.; Hostetler, C. A.; Ferrare, R. A.; Burton, S. P.; Chemyakin, E.; Kolgotin, A.; Hair, J. W.; Cook, A. L.; Harper, D. B.; Rogers, R. R.; Hare, R. W.; Cleckner, C. S.; Obland, M. D.; Tomlinson, J.; Berg, L. K.; Schmid, B. (2014-10-10)We present measurements acquired by the world's first airborne 3 backscatter (β) + 2 extinction (α) High Spectral Resolution Lidar (HSRL-2). HSRL-2 measures particle backscatter coefficients at 355, 532, and 1064 nm, ... -
Characterization of fresh and aged biomass burning events using multiwavelength Raman lidar and mass spectrometry
Nicolae, D.; Nemuc, A.; Mueller, D.; Talianu, C.; Vasilescu, J.; Belegante, L.; Kolgotin, A. (2013-04-16)This paper focuses on optical and microphysical properties of long-range transported biomass burning (BB) aerosols and their variation with atmospheric evolution (ageing), as observed by a multiwavelength Raman lidar, part ... -
Information content of multiwavelength lidar data with respect to microphysical particle properties derived from eigenvalue analysis
Veselovskii, Igor; Kolgotin, A.; Mueller, D.; Whiteman, D.N. (2005-09-01)The multiwavelength Raman lidar technique in combination with sophisticated inversion algorithms has been recognized as a new tool for deriving information about the microphysical properties of atmospheric aerosols. The ... -
Inversion with regularization for the retrieval of tropospheric aerosol parameters from multiwavelength lidar sounding
Veselovskii, Igor; Kolgotin, A.; Griaznov, V.; Mueller, D.; Wandinger, U.; Whiteman, D.N. (2002-06-20)We present an inversion algorithm for the retrieval of particle size distribution parameters, i.e., mean (effective) radius, number, surface area, and volume concentration, and complex refractive index from multiwavelength ... -
Microphysical particle properties derived from inversion algorithms developed in the framework of EARLINET
Müller, D.; Böckmann, C.; Kolgotin, A.; Schneidenbach, L.; Chemyakin, E.; Rosemann, J.; Znak, P.; Romanov, A. (European Geosciences Union, 2015-12-08)We present a summary on the current status of two inversion algorithms that are used in EARLINET for the inversion of data collected with EARLINET multiwavelength Raman lidars. These instruments measure backscatter ... -
Retrieval of bimodal aerosol size distribution with multiwavelength Mie-Raman lidar
Veselovskii, Igor; Kolgotin, A.; Mueller, D. (INST TROPICAL MEDICINE ROTTERDAM - LEIDEN, 2003)The presentation reports on the feasibility to derive microphysical parameters of bimodal particle size distributions on the basis of Mie-Raman lidar instruments consisting of a tripled Nd:YAG laser. Such an instrument ...
